The Manchester United boss, who hasn’t always had the best relationship with the Frenchman, believes his adversary got what he deserved.
Despite the Gunners finishing in fifth last season and a large section of fans demanding Wenger leave the club, the Arsenal boss signed a new two-year deal in May.
And the Red Devils manager believes this was a good decision by the north London side’s senior staff.
Speaking at a press conference in Los Angeles, Mourinho said: “The way Wenger was treated, I think two more years of contract is fantastic treatment.
“That is what every manager wants, to be strong enough to make their own decisions to forget the media opinions, the pundits’ opinions and the supporters’ opinions.
“I think Mr Wenger got exactly what every manager wants. A strong club, two more years of contract and conditions to try to win titles. Fantastic treatment from the Arsenal board. That is what he deserves and that is what every manager wants.”
