The person responsible for pairing Manchester United with Real Madrid in the Champions League qaurter-final, has threatened to sue Sir Alex Ferguson after the Old Trafford boss claimed the draw had been fixed.

Austrian Football Association chief Friedrich Stickler, the man who physically drew United’s name out alongside Real Madrid, warned he might sue.

“This is absolute nonsense. It is incredible. They should take away his title,” Stickler told The Sun.

“How can he say such a thing, I’m speechless. This raises doubts about his integrity and sportsmanship.

“If he does not take that back in an official statement immediately, I will consult my lawyers.”

Ferguson alleged the quarter-finals were rigged so that Spanish teams avoided Italian sides and to give United the hardest possible draw.

Ferguson has subsequently apologised for his remarks, but UEFA could still punish him.

“With his remarks Sir Alex cast doubt upon the integrity of the draw for the quarter-finals,” UEFA said in a statement on Tuesday.

The case will be dealt with by the UEFA Control and Disciplinary Body on May 1.
