The Gunners finished outside the top four last season and failed to qualify for the Champions League, though did triumph over Chelsea in the FA Cup final – the third time they have won it in the last four years.
After much delaying, Wenger’s new contract was finally announced at the end of May, with the club’s hierarchy underlining their belief that he was the best man for the job.
And although Mourinho has had a frosty relationship with Wenger in the past, he is pleased to see a club back their manager and even anticipates he will be fighting for titles over the course of his new deal.
Speaking in LA before Manchester United’s win over Galaxy, he said: ‘Fantastic treatment, that’s what every manager wants, the club to be strong, to be strong enough to make their own decisions and to forget the media and pundits opinion and supporters’ strength.
‘Mr Wenger got what every manager would like, a strong club, you stay two more years of contract, and in conditions to work and try to win titles.’
Mourinho famously dubbed Wenger a ‘specialist in failure’ during one of their many run-ins, though the two managers shared four titles between them last season.
United continued kicked off their pre-season tour with a 5-2 over LA Galaxy, with new signings Romelu Lukaku and Victor Lindelof both making their bows.
