The 50-year-old, who was officially unveiled as new Blues boss on Monday, led Chelsea to their first Premier League title in 2005, dethroning Wenger’s men in the process.
The north London side have only won the FA Cup since their unbeaten season in 2003-04 and have dropped from title contenders to perennial top-four finishers in recent campaigns.
But Mourinho believes Arsenal deserve credit for sticking together through tough times and is adamant Wenger still has the backing of the club’s board, players and supporters.
“I am happy that Wenger is there,” said Mourinho at his unveiling at Stamford Bridge.
“If he’s there, it’s because he wants to be there and the club, fans and players want him there.
“If they stick together and that’s fantastic.
“By not winning a trophy in the last eight years, it shows even more how connected they are.
“I think they’re a great example for a football club, so I’m more than happy.”
Mourinho also rubbished the suggestion that he was disappointed to miss on the Manchester United job after David Moyes was confirmed as Sir Alex Ferguson’s successor in May.
“I am where I want to be,” he added.
“I wouldn’t change it for anything. It’s my job and it’s the job I want. It’s the job I was offered and I accepted immediately.”
