The champions have lost five of their opening 10 Premier League games of the season and in Saturday's 2-1 defeat at West Ham Mourinho was sent to the stands for apparently confronting referee Jonathan Moss
Harris, who made 795 appearances for Chelsea and still works for the club on match days, insists Mourinho, who has been involved in a succession of controversial incidents this term, is still the right man for the job
"They've had one or two important decisions go against them and it's only natural people get a bit irate," Harris told BBC Radio 5 Live's Sportsweek programme
"Jose has always been a winner and, if he sits down and thinks about it today, maybe he could have handled it in a different manner
H e most probably regrets it
"Let's be fair, if you look at his track record where ever he's been, you don't become a bad manager after 10 games, I do the hospitality at the club and I've not seen too many people at Chelsea moaning and groaning
"Maybe they are disappointed with the results, but I'm sure Jose will turn that around."
Former Chelsea midfielder Gus Poyet launched a passionate defence of Mourinho
"It's not the problem of any one person," Poyet told Sportsweek
"You cannot take all praise when you win and you can't be criticised for everything when you lose
"Normally in England unfortunately we go for the head of the manager, but, if you haven't been on the touchline, you don't know how you feel in certain situations
We only look at the bad things
"I do like Mourinho and I have no doubt he will keep his job."
Chelsea Supporters' Trust chairman Tim Rolls says Mourinho retains the backing of the fans, saying: "My message would be keep calm and keep the faith
There's no pressure from supporters for him to go and I've still got faith he will turn it around."
