London: Manchaster United boss Sir Alex Ferguson may face a touchline ban for verbally attacking referee Alan Wiley after his side s 2-2 draw with Sunderland at Old Trafford on Saturday.

Ferguson is likely to be charged by Football Association for accusing Wiley of not being fit enough to referee in the Premier League, calling it an �indictment of our game�. �I was disappointed in the referee I must say.

He didn't add any time on for the goal we scored. He was actually walking up the pitch for the second goal, needing a rest,"The Telegraph quoted him, as saying.

"He just wasn't fit enough for a game of that standard. The fitness of both sets of players, the pace of the game demanded a referee who is fit. He's not fit," he added.

The attack on Wiley was even more shocking as he was the fourth official for the Manchester derby and the man responsible for awarding United the stoppage time from which they got their late winner. Ferguson's criticism didn't stop here he went on alleging that Wiley was using bookings to buy himself a breather.

"It's an indictment of our game. We see referees from abroad that are fit as butcher's dogs. He wasn't fit. He was taking 30 seconds to book a player. I think he's taking a rest, writing down names on his card. It's ridiculous," he said.

Following Wiley's failure to award United a penalty when Anderson and Phil Bardsley tangled in the box, Ferguson spent most of the second half venting his fury on fourth official on Mike Dean.
