Micheal Carrick is adamant that even a 2-0 lead could be overturned if complacency creeps into their game tonight.
Manchester United currently have a 2-0 lead from the first leg and things are looking pretty good for Sir Alex's men to book a final date against Barcelona at Wembley. However, the 2nd leg at Old Trafford is yet to be played and Michael Carrick is imminently cautious about it.

The English midfielder has warned his teammates from letting complacency influence their style of play because Schalke do have what it takes succeed away from home. Remember San Siro?

“It does come into your mind the fact you are two goals up. But it is dangerous to go into a game relying on those two goals to get you through.

“Our approach as always when we play at home is to win the game.”

Manchester United are in a very delicate situation currently with a title-deciding clash against Chelsea coming up this weekend as well. Rumors are strong that Sir Alex will be tempted to ring the changes ahead of tonight's Champions League clash against Schalke.
