Former Chelsea player and coach Ray Wilkins has accused the club's fans of failing to show Jose Mourinho the respect he deserved on his return to Stamford Bridge.
The Portuguese, who spent five seasons in West London across two separate spells, was jeered by certain sections of the home support during Manchester United's 1-0 FA Cup defeat to the Blues on Monday evening.
Mourinho responded by raising three fingers, each one marking a Premier League title won with the club, but Wilkins believes that the whole situation could have been avoided had Chelsea's fanbase shown a "bit more class" to the self-proclaimed Special One.
"I just wish our Chelsea supporters - and I'm a Chelsea supporter - showed a little bit more class to Jose Mourinho," he told Sky Sports News. "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's employed by Manchester United. Chelsea relieved him of his post. If we actually remember what he's done for our club, and I say our club because I've been a Chelsea man since I was 10-and-a-half, he's worked miracles there.
"He's a good bloke but he's 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."
Mourinho, who also won three League Cups and an FA Cup during his time at Stamford Bridge, hit back at the 'Judas' jibes following his side's defeat.
