If you are a kid and an experienced manager like SAF tells you "have patience", the wise thing to do is to listen to him. If you don't listen to him and you go away, this is a clear indication of future problems. This was such a huge red flag, I still cannot understand why the club paid so much to bring him back. Blunder number one.
If you own an expensive player, you simply don't let him run into his last year of contract. You either sell him or extend long before that. Blunder number two.
Now we got ourselves in such a situation where the player holds all the cards. We can't blame him, it is gross mismanagement on our part. But it is certainly not a surprise that we constantly run into problems with this player, it was evident long time ago.
Well Said, Under Ed our main motive was earning lot from sonsership deals and Pogba is 4th most marketabl;e player in the world, so no wonder we are tolerating so much in his case
