The Special One hit back at the Blues supporters by holding up three fingers in reference to the number of Premier League titles he won in west London.
And former Chelsea player and assistant manager Wilkins believes Mourinho deserved better treatment.
“I just wish our Chelsea supporters showed a little bit more class to Jose Mourinho”
Wilkins said: “I just wish our Chelsea supporters, and I’m a Chelsea supporter, showed a little bit more class to Jose Mourinho.
“He is a good bloke but he is a football man, he wants his club to win.
“I just thought the other night against Manchester United they didn’t show him the respect he merits.
“People will naturally be thinking: ‘Hang on a second he was demonstrating stuff on the touchline against Chelsea’. Well yes, he was but now he is employed by Manchester United.
“Chelsea relieved him of his post. If we actually remember what he has done for our club, and I say our club because I have been a Chelsea man since I was 10 and a half, he has worked miracles there.
“I think they [Chelsea fans] do [think he is still number one] if they are thinking about it logically and sensibly.
“There is no one that that can touch him at the moment. Jose will be number one until somebody wins as many trophies as Jose.”
