Higlights: Chelsea 3-1 Rubin Kazan
Chelsea will take a two-goal advantage to Russia after beating Rubin Kazan in the first leg of their Europa League quarter-final, on a night when Tottenham fought back from two goals down to claim a 2-2 draw against FC Basel at home.
Newcastle United, meanwhile, will need a memorable night at St James' Park if they are to reach the semi-finals of the competition, after falling to a 3-1 defeat to Benfica in Lisbon on Thursday.
At Stamford Bridge, Chelsea claimed a 3-1 win over Rubin Kazan thanks to two goals from Fernando Torres - but Bebars Natcho's 41st-minute penalty will give the Russians some hope going into the return meeting.
Torres, wearing a protective mask once again, broke the deadlock with a scrambled first-half finish, before Victor Moses doubled the Blues' advantage with a well-taken volley from the edge of the box.
Natcho then grabbed a potentially crucial away goal from the spot after John Terry was adjudged to have handballed a shot but, in the second half, Torres gave manager Rafa Benitez some breathing room - powering home a close-range header.
At White Hart Lane, meanwhile, Tottenham's recovery to claim a 2-2 draw against FC Basel was marred by a serious-looking late injury to Gareth Bale.
Gareth Bale was stretchered off in injury time with his leg in a protective brace after jarring his ankle in an awkward collision, after Emmanuel Adebayor and Gylfi Sigurdsson had both scored to bring Andre Villas-Boas' side back from 2-0 down.
Benfica came from behind to beat Newcastle United 3-1 in Lisbon.
Papiss Cisse gave the visitors the lead, and went close to doubling their advantage when his shot was tipped onto the inside of the post, but Rodrigo fired home for Benfica to ensure the scores were level at the break.
Cisse then struck a post again shortly after the restart, but Benfica took control of the tie when Davide Santon's poor backpass allowed Lima to score, and Oscar Cardozo then converted a penalty after Steven Taylor was penalised for handball.
In the other quarter-final, Fenerbahce edged Lazio 2-0 in Turkey thanks to Pierre Webo's second-half penalty and Dirk Kuyt's late finish.
