The Blues boss admits it would be a shock if they would get anything from the game.
“If it was only about me and the boss then it might be a more even fight, but he has got untold riches in terms of ability, financial clout, technical ability, speed, strength,” he said.
“He has everything. They are a top, top club in everything they do.
“For us to compete with Manchester United is going to be very difficult but that is the challenge that faces every team that plays them.
“They are the champions – everywhere they go they are feted – and we are going into the lions’ den this weekend.
“Our players will need to punch above their weight.”
