Fabio Capello feels Chelsea boss Antonio Conte has been taken aback by his verbal battle with Manchester United rival Jose Mourinho.
Capello believes Conte is struggling in his nasty row with Mourinho.
He told Sky Italia: "I think Conte did not understand who he was dealing with, he should have said that it is Chelsea's shirt that makes the coaches shake.
"They're both out of control and I did not think it could get to that point.
"But Mourinho is good at all dialectic situations and maybe even this time he wants to divert attention from his team."
