ALEX FERGUSON has told his Manchester United side to cut out the defensive errors if they want to make progress in the Champions League.
United are in Romania tonight to face CFR Cluj.
But United take a dreadful defensive record with them, having gone three games without a clean sheet and conceding three goals in their last outing.
"When you consider the first half against Southampton, the first half Liverpool and first half on Saturday, we have some work to do," said Ferguson.
"You have to be concerned losing goals the way we did. It's not planned but I think it will be the last.
"After the first half on Saturday I had plenty of concerns.
"I hope it's an awareness thing because we faced this situation at the end of October last season, and from then on when Jonny and Rio played together consistently we played better."
