Man Utd did go for Klopp.Man. Utd supporter here. As much as it pains me I have to say Klopp is a magnificent manager and has done what the best managers do. Built a championship winning team and then saw it was getting stale and has built another one. Utds mistake was not going for him when they could. He's the nearest thing to Ferguson around today.
But like Ferguson,who ran every part of OT, it is an all consuming job the pressure is immense even more so now with social media. Fergusons kid tell of how they never saw their Dad. The toll on one's health must have a part to play, Ferguson has a pacemaker and suffered a stroke. Gérard Houllier died of a heart attack, even Shankley and Stein went before their time and Clough became an alcoholic. I'm not saying football was the cause but their way of management was certainly a factor.
Klopp realises this and I don't blame him one bit for taking a rest. Life is for living with your loved ones and I wish him all the best.
