Sir Alex Ferguson admitted Paul Scholes had another of his "red-mist moments" after the midfielder was sent off in Manchester United's FA Cup semi-final defeat against Manchester City.
Scholes was dismissed for a thigh-high lunge on Pablo Zabaleta as United tried to fight their way back into the clash at Wembley.
The red card proved costly, with City holding on to win 1-0 to end their arch-rivals' treble bid and reach their first cup final for 30 years.
United boss Ferguson insisted Scholes' sending off "didn't kill the game" because the 10 men piled on the pressure in the closing stages.
But he added: "We've seen over his career Paul has had unbelievable moments - he's one of the greatest players this club has ever had. But he has his red-mist moments - he caught the boy on the thigh."
