Fabio Capello is surprised Manchester United boss Jose Mourinho and Chelsea counterpart Antonio Conte have let their public feuding get to its current level.

The Italian believes his fellow countryman Conte may have made a mistake to use the word "senile", which a club spokesman later confirmed was meant to mean "amnesia", as the Chelsea manager admitted his feud with the United boss is "personal" last week.

Capello said: "It is the Chelsea jersey that makes managers nervous. We all remember anxieties when he (Mourinho) was the Chelsea manager.

"Conte has been doing exactly the same as Mourinho. We all remember Mourinho kneeling down in the middle of the pitch or Mourinho running after a win.

"I think that Conte has not realised who he has been dealing with yet. In my opinion, he should have said just one thing. If Conte used the 'senile' word he certainly made a mistake.

"However, I think that Mourinho is such a good debater, and maybe also this time he has been trying to divert the attention from his team.

"They are totally out of their minds. I didn't imagine they could go this far."
