There were mixed fortunes for Barclays Premier League sides in the Champions League as Chelsea won 1-0 in Porto while Manchester United suffered a surprise 0-1 defeat at home to Besiktas.

Nicolas Anelka stunned Porto for the second time this season as Chelsea finished top of Group D with a 1-0 victory in the Estadio do Dragao.

Anelka, who scored the winner when the two teams met at Stamford Bridge, stooped to head home a cross from Florent Malouda in the 69th minute.

It was an efficient rather than exciting performance from the Blues who had the woodwork to thank in the first half when Fernando Belluschi's 25-yard effort smashed off the crossbar.

already through

Manchester United fielded a young side as they went down 0-1 against Besiktas at Old Trafford knowing they were already through to the knock-out stages.

Sir Alex Ferguson's men needed only a point from this match to top the group thanks to CSKA Moscow's 2-1 win against Wolfsburg earlier in the day. It was a result which also killed off any lingering hopes of Besiktas qualifying.

However the Turkish side took a shock lead after 20 minutes as Rodrigo Tello hit a 25-yard shot which took a slight deflection off Fabio to evade the dive of Ben Foster.

The visitors hung on against increasing United pressure in the second half with goalkeeper Rustu making two fine saves in stoppage-time.
