Jose Mourinho's sacking "will tarnish him", says Match of the Day pundit and former England striker Alan Shearer.

"Nothing surprises me with football managers nowadays," Shearer tells BBC Radio 5 live.

"I have never known a capitulation like it from a football club. I have never known players perform like they did in a season and then be so bad now. It is unbelievable.

"It will without doubt hurt him. He tried leaving players out that didn't work. He tried criticising players in public, that didn't work. He tried protecting players, that didn't work. Whatever he has done it just has not worked. No one could have predicted this."
