The two legends are two of the longest serving managers in the history of the game, and also for their own respective clubs.
While Sir Alex was still a manager, he enjoyed some fierce and memorable battles with Wenger on the other side of the touchline. Their relationship wasn’t the best at the start, but they soon patched up and became very good friends in the game.
While Sir Alex retired after winning the title back in 2013, Wenger has rather been pushed out of the club despite his 22 years of service.

“I am really happy for Arsene Wenger,” Sir Alex told ManUtd.com. “I have great respect for him and for the job he has done at Arsenal.
“It is great testament to his talent, professionalism and determination that he has been able to dedicate 22 years of his life to a job that he loves.
“In an era where football managers sometimes only last one or two seasons, it shows what an achievement it is to serve that length of time at a club the size of Arsenal.
“I am pleased that he has announced he is leaving at this stage of the season, as he can now have the send-off that he truly deserves. He is, without doubt, one of the greatest Premier League managers and I am proud to have been a rival, a colleague and a friend to such a great man.”
