Manchester United 0 Besiktas 1
Manchester United's 23-match unbeaten home record in the Champions League was shattered by Turkish side Besikas on Wednesday.
Rodrigo Tello's first-half effort did the damage, but a point at Wolfsburg in a fortnight will still secure top spot in Group B, qualification having already been achieved.
Chelsea win group
Nicolas Anelka's second-half header earned Chelsea a 1-0 win against Porto and guaranteed the English side will win Champions League Group D with one match still remaining.
The goal came from a simple move in the 69th minute. With the Porto defenders static, Yuri Zhirkov fed Florent Malouda on the left wing and the Frenchman crossed for his compatriot Anelka to head in unchallenged.
Porto, who like Chelsea had already qualified for the last 16, had the best chance of a tame first half when Argentine midfielder Fernando Belluschi sent a shot crashing against Petr Cech's bar.
The Premier League leaders showed more intent at the start of the second half and playmaker Deco almost netted against his former club on 52 minutes, collecting Rolando's flawed clearance but shooting just wide.
