Jose is coming across as a bit of a bully without class. There is times for conversations and there is also places for conversations. Whether this is a media beat up is debatable.
Googling Jose Mourinho reveals some Rashford related gossip, but only from Metro.
Aside from the fact that it's probably horseshark I wouldn't blame him. Rashford can become one of the world's best strikers and he isn't going to do that from left-wing / the bench.
So you play him regardless? Rashford is good but not one of the worlds best strikers right now. Massive potential, but too inconsistent.
