Manchester United lost their 100% record in the Champions League this season with defeat at Galatasaray.Striker Burak Yilmaz scored his fifth goal of the group stage early in the second half when he leapt highest to head in from a right-wing corner.The home side created the best chances, with Anders Lindegaard saving from Yilmaz and Hamit Altintop, who also saw a shot rattle the United woodwork.Teenager Nick Powell had United's best chance when his header struck the bar.With Cluj beating Braga, it was essential for Fatih Terim's side to secure victory over the three-time European champions.Those two sides have seven points and are both vying for second spot, while United remain on 12 points, having already won the group.With qualification for the last 16 secured and having left several senior players at home, this encounter gave Sir Alex Ferguson the chance to see if the next generation could cope in an intense atmosphere.Of particular interest to some United fans would have been the performance of those competing for a spot in central midfield.Long-serving United pros Ryan Giggs and Michael Carrick looked leggy against Norwich in last weekend's 1-0 defeat, with Ferguson bringing on a 38-year-old - in the form of Paul Scholes - to try to remedy the situation after his side fell behind.Those two sides have seven points and are both vying for second spot, while United remain on 12 points, having already won the group.With qualification for the last 16 secured and having left several senior players at home, this encounter gave Sir Alex Ferguson the chance to see if the next generation could cope in an intense atmosphere.Of particular interest to some United fans would have been the performance of those competing for a spot in central midfield.Long-serving United pros Ryan Giggs and Michael Carrick looked leggy against Norwich in last weekend's 1-0 defeat, with Ferguson bringing on a 38-year-old - in the form of Paul Scholes - to try to remedy the situation after his side fell behind.
