A few days ago, Chelsea former player Steve Sidwell talked about his interesting stories when he played for Mourinho.

Sidwell said: "I am a midfielder. When I first joined, Mourinho asked me if I would mind wearing the No. 9 jersey. I said it was OK and thought he was testing me. As a result, they really gave No. 9. When I told my friends, they couldn't believe it at all, after all, I was not a forward."

"He gave me No. 9 jersey, which was actually Mourinho's way of conveying information to the management. Because he wanted to buy a forward, the board refused to provide funds, so he gave No. 9 to a player who joined from Reading at zero cost."

This contradiction eventually broke out. After leading the team in eight games at the beginning of the 2007/08 season, Mourinho, who led the Blues to the Premier League championship twice, left the team. Sidwell, who temporarily put on the No. 9 jersey, only played for the club that season, scoring 1 goal 25 appearances.
