Sir Alex Ferguson and Arsene Wenger had a bit of a bumpy relationship on the touchline. Ferguson, the legendary Manchester United manager, saw the Red Devils through a period of dominance that stretched through much of his tenure at Old Trafford which saw him break the Invincibles undefeated streak (for which Cesc Fabregas reportedly threw a piece of pizza at him), shellack the Gunners 8-2 in late summer 2011, and purchase Arsenal's world class captain Robin Van Persie. Clearly, he got the better of Arsenal on a few occasions - but despite all his accomplishments, he does not have a golden Premier League trophy in his cabinet while Arsene Wenger does.
Today, the now-retired Ferguson has heaped praise on the Arsenal manager in the matchday program for the Champions League Final.
"He (Wenger) has been fantastic," Ferguson was quoted as saying in the Champions League 2016 final programme.
"Now he gets a lot of criticism, but I admire that you're not going to bend to the will of the critics. He stays with what he believes in. And I think people who do that are outstanding coaches.
"When you talk about consistency, Arsene's never changed the way that his side has played."
Ferguson has always been an admirer of Wenger's eye for talent and appreciates the style of football he sets his teams out to play.
Ferguson said: "I think he inherited a team when he first came to Arsenal with Steve Bould and Martin Keown and Tony Adams - fantastic warriors - but his team evolved when they started getting players like Thierry Henry, Robert Pires, Emmanuel Petit and Sylvain Wiltord.
"There was a change in the culture of the team. They became a magnificent team. Arsene has never changed in the type of player he wants or the sort of play he wants.
"It's always about penetration from runners off the ball, good passes into angles for the strikers."
You can say what you want about the former United boss - and plenty of people have - but he certainly is a talented man who knows soccer, and he very clearly has a great deal of respect for Arsene Wenger. So should we all, irrespective of whether or not we think he should stay or go.
