"Joe Cole's tackle was the type of tackle that puts players out of the game.
"That was a red card, but he only gets a yellow because they already had a player sent off."
He said: "The second penalty was harsh, but it cancelled out the first.
"Referees can get things wrong, but it didn't affect the result.
"We were the better team. We've got our confidence back."
The style and the tempo were back.
"Our football in the early parts of the match was outstanding - in the first half-hour we played as well as we have all season in terms of the penetration of our play, the movement and our passing.
"We could have been two or three up early on. Petr Cech made a great save from Wayne Rooney right at the start and we were dominant at that point.
"I think the real turning point was the goal just before half-time. It was a real blow to Chelsea. At that point we had complete control of the match."
Avram Grant has more reason to feel unhappy.
Grant said: "There were so many things - the sending-off, the fact that they signalled two minutes of extra-time and scored after three, and the penalty,"
"Sir Alex Ferguson can be more than happy with the referee. The referee tried his best but he made three mistakes; the red card, their first goal and the penalty. I am also surprised Rooney was not shown a second yellow card.
"Maybe I am being naive but I wonder what Sir Alex's reaction would have been if he was in my position."
