Mourinho is the type of manager who panic buys with astronomical amounts of cash to try to save his reputation, instead of waiting 1 year for a super talented kid to develop, like Fergie always did or Ole is doing. Jose will always put No. 1 before long term health of a club. And he'll always blame everyone but himself when things don't work out.
Jose miraculously managed to clear most of the garbage left by Van Gaal - Schweinsteiger, Memphis, Schneiderlin... . Mata and Fellaini somehow survived but should have gone too.
But Jose proved he's yesterday's man with terrible signings himself. The 250 million spent on Fred, Matic, Mkhitaryan, Sanchez, Bailly, Pogba was a terrible waste of money. Reckless short-termism from a guy who wants to win a trophy today whatever the cost, without any regard for tomorrow.
Let's always remember that Jose was desperate for another 300 million to sign a few more players with only 1 good year left in them - William, Peresic, Jerome Boateng, Nainngolan etc
