You should stop listening to the media and to united fans. the fanbase have this huge favoritism towards some of the players and they crucified mourinho because he dares to drop those player as if they understand football better than someone with 25 major trophies throughout his career. Now tell me what did they have won since he left ? What did they have won since Martial, Pogba and Rashford start playing regularly with freedom and smile on their face ? Nothing , so how can anyone said Mourinho was wrong to drop them ? Rashford didn't turn up when it matters, Pogba didn't turn up when it matters, Martial didn't turn up when it matters, they bottled all the 3 semifinal they got in last season. The media may paint Mourinho as some kind of finished dinosaur coach but trust me, the only one finished is Manchester United Football club , with their incompetent management and board who decide who to play based on popularity votes not Mourinho. Mourinho prefer players who gave 6-7 / 10 each game than players who drop 8-9 and then 2-4 the next game, it's about being consistent which is why he loved Matic and Fellaini back then which is also why Harry Winks played regularly too, because consistency is what a squad needed to win the league, those players who only good for 1-2 games does look nice on youtube compilation though. About game management yesterday against southampton, notice how Mourinho not only manage the style and pattern to play , he also manage his player stamina, he realized soton would have run out of their gas in second half after running around the pitch for the first 45 minutes and told kane to drop deeper to feed son through ball and rip them apart in second half. He is tactical genius who only focused at winning the game , and as long as the players buy into his idea , He will definitely delivers.
