Arsenal also celebrated a victory in their group after a late strike by Danny Welbeck secured a 1-0 win over Sporting in Lisbon, while Real Betis pulled off the shock of the evening with a 2-1 win at former European Cup winners AC Milan.

The 22-year-old England international made it 3-0 with a sublime finish in the 54th, side-footing into the bottom left corner from 22 metres after taking a loose ball in his stride.
BATE right back Aleksey Rios netted a 79th-minute consolation for the visitors, whose goalkeeper Denis Scherbitski made several fine saves in the second half.
The result left Chelsea top of Group L with a maximum nine points, while BATE, PAOK Thessaloniki and Hungary's Vidi are locked on three each after Vidi enjoyed a surprise 2-0 win at PAOK.
Arsenal forward Welbeck struck the 79th-minute winner at Sporting with a crisp low shot from 15 metres through the legs of goalkeeper Renan Ribeiro, who had produced a string of good saves in a fast-paced contest.

Milan's miserable week continued following Sunday's 1-0 Serie A defeat by city rivals Inter as goals from Betis' Antonio Sanabria and Giovani Lo Celso condemned the Italians to their first Europa League setback after two wins in Group F.
Sanabria silenced the San Siro crowd when he bundled the ball home from point blank range on the half-hour and Lo Celso netted a thumping long-range shot shortly after the break.
Patrick Cutrone pulled one back for Milan with an 83rd-minute solo effort but it was too little too late for the winners of seven titles in Europe's elite club competition.
