Rodrigo Tello's deflected first-half goal defeated a youthful Manchester United as Besiktas ended their 23-game unbeaten sequence at Old Trafford in the Champions League.
Sir Alex Ferguson - with qualification for the last 16 already assured - fielded an experimental line-up and gave some of Manchester United's young brigade a chance to shine on the big European stage.
Gabriel Obertan was the most promising of the Old Trafford undercard, but the inexperience of a side also containing Danny Welbeck, Federico Macheda, Rafael da Silva and Darron Gibson was exposed as they failed to turn long periods of territorial domination into an end product.
And that long run without a loss, stretching back to when AC Milan won 1-0 at Old Trafford in February 2005, was broken when Tello's long-range strike after 20 minutes took a touch off Rafael and beat keeper Ben Foster. (BBC Sport)
