It's obvious he's not satisfied with his current squad.
That's the correct point. Amorim has indicated that he's not feeling confident with the current squad and doesn't meet his expectation. He's signalling INEOS to give him actual transfer like what he wanted. He tried his best with the current squad, but too many mediocre players in the squad.
There are lots of changes have to be made to his current roster now. I'm doubting this can be done in a short time.
Does this indicate that Man United will be very active in the January transfer window? because if he doesn't get rid of some of those slackers then Amorim will just complain about the same thing over and over again. However, it is clearly not easy to release players to other clubs because the biggest problem is that they get big salaries at Manchester United, so they may not be willing to leave if the club that wants to sign them cannot meet their demands.
