Manchester United boss Louis van Gaal has played down his influence on Chelsea manager Jose Mourinho.
Chelsea meet United tomorrow.
Mourinho often credits a lot of his success to Van Gaal and his other mentor Sir Bobby Robson, but the Manchester United manager thinks the main reason behind Mourinho's success is the man himself.
"He talks about Louis van Gaal and also Bobby Robson, and I appreciate that, but you always do it by yourself," Van Gaal said.
"I was also an apprentice when I was the assistant coach of Leo Beenhakker (at Ajax) and it's good that my eyes were also open at that time.
"And it's good that Jose Mourinho's eyes were very open when he was my assistant, but you do it by yourself."
