Sir Alex Ferguson is scared Manchester United's cartoon defending is going to prove very costly in Sunday's Manchester derby.
Ferguson appeared to dash hopes of Nemanja Vidic returning to lend a hand when he ruled the Serbian out of tomorrow's Champions League encounter with CFR Cluj at Old Trafford.
United need some sort of assistance, though. In conceding 32 goals so far this season, including three in quite awful fashion at Reading on Saturday, Ferguson said he could not remember a time when his side's defence had been so leaky this side of Christmas.
It was actually 2001-02, when United conceded 39 goals in their first 23 games, and 41 before Santa made his way down the chimney.
Clearly, though, it is no laughing matter for Ferguson, especially when he considers what is lying in wait on the other side of town this weekend.
"It is a worry," said Ferguson. "If we perform like that on Sunday then God knows what's going to happen to us.
"We've lost 32 goals already - I can't remember us losing so many goals before Christmas.
"Saturday was like Cartoon Cavalcade and when you see City have Balotelli, Dzeko - really tall players - it's going to be a big challenge.
"It's a concern. But that's on Sunday. It's five days away but at this moment in time it feels like five months."
