"You have to give a lot of credit to Birmingham City, they put in so many tackles that we weren't allowed any time on the ball and couldn't get any rhythm into our game." the United boss said after the 0-0 draw at St Andrew's.
"They kept coming forward all the time and competed for the entire game.
"We kept our composure and emerged with a point.
"We had our chances like the one from van Nistelrooy in the first half when their goalkeeper made a good reflex save."
