Andre Villas-Boas has challenged Tottenham to show they are capable of cutting it in the Champions League by beating Lyon.
Villas-Boas will take one more step towards securing his second Europa League trophy if Spurs overcome Les Gones in the first leg of their last-32 tie against the French club at White Hart Lane.
While manager Villas-Boas regards the competition highly, chairman Daniel Levy, and the club's fans, would surely forfeit their place in the Europa League if it meant the London club qualified for the Champions League next season.
Spurs supporters long for a return to the biggest club competition in Europe following their heroics in the competition two seasons ago when they reached the quarter-finals, and the team are currently on course for qualification via the Barclays Premier League, where they sit in fourth with 12 games to go.
Given that Lyon possess such stars as Lisandro Lopez, Yoann Gourcuff and Bafetimbi Gomis, Villas-Boas believes Lyon should be playing in the Champions League - indeed they reached the last four of the competition just four years ago.
For that reason, he thinks the two fixtures could go a long way towards proving whether his men should also be competing among Europe's elite.
``This could be a test of whether we're good enough to play in the Champions League,'' he said.
``I think we've been handed the most difficult draw of this knock-out phase. This is like a Champions League tie.
``Lyon represent a club with tremendous Champions League experience in recent years.
``It will be a good test for Tottenham. It's always going to be a learning experience for us and I think it can serve that purpose towards the future, that's for sure.''
Villas-Boas has a selection quandary in defence, with Michael Dawson, Steven Caulker and Jan Vertonghen all vying for a place in the team alongside expected starter William Gallas.
Gallas started most of Tottenham's games in the first half of the season, but has struggled to win his place back following a calf injury, with Dawson impressing in the Frenchman's place.
Remi Garde, meanwhile, wishes he had been alerted to Gareth Bale's talents earlier - so he could have tried to lure the Tottenham winger to Lyon.
The 23-year-old has scored five goals in his last four matches to take his tally for the season to 19 - comfortably his best return since he made his bow in 2006.
Lyon boss Garde, needs no reminding of how deadly the Welshman can be. The 46-year-old was informed about Bale's talents by former Lyon youth director Georges Prost, who held the same post at Southampton from 2002-2007 when the winger was at the south-coast club.
Back then Bale was just a gangly left-back, but Prost was still convinced the wide man was set for stardom.
``Georges Prost worked with Gareth as a youngster at Southampton,'' Garde said.
``He told me a few years ago about him, but he was about 16 at the time and he had already made his debut for Southampton. He was a young man but he was already expensive then, too expensive.
``Prost told me how quick he was then, how much skill he was blessed with even at that age, so it's not a surprise to me to see the top form Gareth has been in.
``He is the sort of player that we do need to keep an eye on.''
Spurs and Lyon are linked by goalkeeper Hugo Lloris, who moved to England for £12million last summer.
Lloris has been in superb form of late, but Villas-Boas revealed that Brad Friedel will start in goal ahead of the France captain, much to Garde's disappointment.
``I suppose it's kind of a regret (that Lloris is not playing). It is for all of us,'' Garde said. ``He was very much loved at Lyon. He made a big impression.''
