Man Utd boss Ferguson sure to face FA wrath after amazing linesman attack
Ferguson was steaming after Beck turned down Wayne Rooney's penalty appeal at Tottenham.
And his mood worsened as Clint Dempsey hit a 92nd-minute leveller.
Fergie said: "The linesman on that side of the pitch didn't give us a thing all day. For me, it was a poor performance by him. Why he never saw the penalty kick from Wayne Rooney, some other decisions, I don't know.
"He had a shocking game again and I'm disappointed in his performance, I really am."
Beck incurred Fergie's wrath when he failed to flag for offside against Chelsea striker Drogba as he scored the Blues' winner in their 2-1 victory over United at Old Trafford in April 2010.
