United fans will be celebrating this decision without realising Mourinho is one of the few managers out there that plays even worse football than LVG. They'll probably win a few trophies in the immediate future that they shouldn't do but it will be short lived and will be detrimental to them in the long run.
In a few years time, Pep will have hopefully transformed us into something formidable, Chelsea should be back up there after the mess Mourinho left them in, Arsenal will probably be rid of Wenger and can start challenging again, Spurs look like going from strength to strength under Pochettino and even Klopp might get Liverpool competing, then over at United Mourinho will leave them in the shit and miles behind. This could be brilliant
