Darren Fletcher admits Manchester United's poor defending will eventually catch up with them.

United went 2-0 down against Braga last night before winning their Champions League tie 3-2.

Fletcher said: "We know we can't keep doing it. If you take away the first when we went 2-0 down it was a good performance.

"People will talk about slow starts and giving away early goals but the fact we came back to win showed great character."
