And that is that, the reigning Champions of Europe have reached the Europa League final and stand a chance of holding both trophies at once.
Moses breaks after winning the ball from Sauro, he plays the ball out wide to Oscar who overhits his cross out of play.
Three minutes of added time for Chelsea to see out.
Basel fans have unveiled a huge banner of their colours accompanied by some flares. They are determined to depart the competition with a bang.
Serey Die finally goes in the book for a foul on Oscar. He's committed several tonight already.
Basel coach Murat Yakin has taken his place on the bench, arms folded, resigned to defeat.
Chelsea are reduced to harrying and hassling Basel in their own half, seeing out time, but happy to do so.
Bertrand is tackled in the box but before the ball is cleared Torres is on the case to first win it, then lay it off for Mata who curls a shot and draws a save from Sommer.
What a stage for teenage Dutchman Nathan Ake to be given a chance on.
Goalscorer Luiz is taken off for youngster Nathan Ake.
Another long range effort from Basel, this time from Diaz. They have run out of steam now and are resorting to shots from distance.
Chelsea's third and final sub will see Ake come on shortly. Likely to replace Luiz.
Another Basel effort from distance is deflected by Ivanovic before being pushed wide by the outstretched arms of Cech.
Serey Die tries his luck from outside the box and his low shot forces Cech into a save but not a particularly strenuous one.
Great work from Oscar down the right, the Brazil international makes space and bounds into it before crossing for Torres who is tackled as the ball reaches his foot.
Frei makes way Diaz in Basel's final sub.
And there is the sub to loud applause all round. Hazard off, Mata on.
It looks like Hazard will soon be subbed for Mata.
Hazard shows great vision by spotting Sommer off his line and tries an audacious lob but the goalkeeper is able to recover and claim the ball.
The second corner is straight into the arms of the grateful goalkeeper Sommer.
Torres wins a corner which Oscar takes towards Luiz but he is beaten to it and Chelsea win another corner.
Fernando Torres celebrates his goal against FC Basel
The game has slowed down a lot since Luiz put Chelsea 3-1 up on the night.
The pitch opens up and Elneny is presented with an opportunity to shoot from the right side of the box but it is hit over the bar.
Lampard hits it, with hopes of becoming Chelsea's joint all-time top scorer, but he kicks well over the bar.
Lampard and Luiz over the ball.
Schar is booked after grabbing Torres and dragging him down outside the area.
Ramires is subbed for Oscar.
Chelsea have taken their foot off the gas, possibly with one eye on Manchester United this weekend, and are allowing Basel forward within reason.
I wonder, with the game nearly out of sight, if Benitez will consider taking off Bertrand, Ramires or Luiz. All three will miss the final if they receive one more yellow card.
Frei turns into space on the edge of the box and before anyone from Chelsea can get close he hammers a shot against the frame of the goal. Cech wasn't close.
BASEL HIT THE BAR
A second sub for Basel, Degen comes on for Stocker.
Ha Streller is withdrawn for Basel, who bring on Zoua.
The Blues' aggregate lead is three goals. (5-2)
Chelsea are running riot now.
David Luiz puts the game beyond doubt, and Chelsea out of sight, with a sublime first time left foot shot that curls into the top corner.
GOAL FOR CHELSEA
All of a sudden Chelsea are full of adventure and invention. Basel will have a job on their hands to pick themselves up and turn this around now.
Would you believe it, Chelsea go close again as Ramires fires the ball across the six-yard box and the ball is almost knocked in from close range by a defender.
On aggregate it is 4-2 to Chelsea who scored two goals that were two minutes and 23 seconds apart.
Moses has now scored home and away in the Europa League quarter-finals and semi-finals this season.
Moses gives Chelsea breathing space after Torres' shot is blocked and falls into his path allowing him the chance to score from close range.
That has stirred the crowd who are in full voice.
That goal doesn't change much for Basel, they needed a second goal to qualify anyway. And they still do. It could give the hosts a huge lift though.
A special mention must go to Hazard's industrious running at the Basel defence which opened the chance up in the first place.
The man in the mask hits his 20th goal of the season, and eighth European goal of the season after Lampard's shot is spilled at his feet allowing him a tap-in.
Torres and Hazard combine but neither can find a way through Basel's wall of white shirts which blocks the Blues out.
This is also Rafa Benitez's sixth semi-final match in just over six months in charge at Chelsea. That's some going.
No changes for Chelsea at the break in what is their 64th game of a bumper campaign.
The teams are out for the second half and it is Chelsea, shooting from left to right, who will get us underway.
With Mata and Oscar on the bench the Blues have something in reserve but they will need to be more clinical in the second half if they want to make this comfortable.
So, Chelsea, for all their possession and threat in the first half, failed to create any number of real openings and are made to pay for their profligacy by Basel.

Fear not Chelsea fans, as it stands at the moment the Blues will progress on away goals.
And that is the last action of the first half. Chelsea troop off the pitch, stunned. While Basel walk off in a haze of glory and with a vital away goal.
Stocker is given time to pick a pass in front of the static Chelsea defence and plays in Salah, who beats the offside trap to slot past Cech.
GOAL FOR BASEL
Ivanovic finds Torres, the Spaniard cuts inside one, then two and shows great skill as he lines up his shot on goal...but he gets it all wrong and hammers the ball out for a throw-in!
More magic from Moses attempts to drill the ball across the face of the goal from the left but it is blocked out by Basel.
Big penalty call for Basel is turned down. The shot strikes Bertrand in the shoulder but the visitors' players all claim it to no avail.
Basel are working hard to try and reclaim a foothold in the game. There is a real energy and purpose to their game all of a sudden.

Corner for Basel after Cahill is called into action by a swift through ball. The danger is quickly averted though as Cech catches the cross easily.

Cahill, by the way, walked away seemingly unscathed.
Stocker of Basel is walking with a limp after a fullblooded challenge from Cahill took first the ball, then every bit of the man and sent him crashing to the floor.
Basel are defending in numbers and leaving just two men forward at any time in an effort to smother Chelsea's frequent attacks.
Chelsea have slowly taken control of the game and are now enjoying all of the meaningful possession while Basel are restricted to half-chances and hopeful punts forward.
The corner flies through the box before landing at the feet of Luiz at the back post who swings at the ball but doesn't make contact.
Torres pulls wide to the left wing, cuts in and plays a neat one-two before shooting towards the corner and forcing Sommer into a save at full-stretch.
A third foul of the evening by Serey Die, this time on Hazard.
Hazard's angled cross from the left wing is aimed towards Ramires but Basel goalkeeper Sommer comes to claim confidently.
Jose Mourinho's name has been chanted around Stamford Bridge for the first (and probably not last) time this evening.
Surely these two sides will not keep up this energetic pretence for too long. Both are desperately contesting every ball with barely a pause for breath.
Ivanovic is across quickly to nip the ball away from Steinhofer and concede a throw-in. Excellent defending.
Torres knocks the ball over the top of the Basel defence and Lampard stays onside to run clear before hitting a shot against the post - so close for Chelsea.
LAMPARD HITS THE POST
Basel's Serey Die has just given away a second free-kick for a cynical challenge on Bertrand, it was he who fouled Moses too. He might need to be careful now.
Hazard bends the ball across the face of goal but it is headed away.
Victor Moses wins a free kick for Chelsea almost on top of the corner flag on the left wing. Moses stood up to the physical defending of Basel well there.

There are a fair few Basel fans filling the away end with colour this evening, on a crisp, sunlit evening.
The teams are in the tunnel at Stamford Bridge and the crowd are in good voice. We're just moments from kick off.
He continued: "We play against a very good team, a team who have scored goals away from home, so everyone has to realise it will be tough, difficult. Hopefully I will be wrong and we will score a lot of goals and go through."
In a pre-match interview on ITV, Rafa Benitez has warned against complacency this evening. He said: "We have an opportunity but my concern is that we will be thinking we are in the final."
Remarkably, this is the fourth competition that Chelsea have reached the semi-final in this season. The others being the League Cup, the FA Cup and the World Club Cup.
Frank Lampard has taken the captain's armband for Chelsea tonight. With John Terry on the bench is that a sign that he could be in line for a starting berth against Manchester United on Sunday?
