No one was in form before the Newcastle game, so I don't understand why people are blaming only Mkhi here. Mata and Mkhi are different players, Mkhi wants to be involved in the attack more than to sit back and defend and Mata doesn't mind even if he has to defend. I never told Mata doesn't defend. No one was saying anything when he was getting assists at the start of the season, when the whole team started playing badly everyone started bashing Mkhi. Freedom? Really? He hasn't been allowed to use his pace, by the time he gets the ball the other team players get back in position to defend.
The bolded part is exactly the reason why Mata has been getting this much of game time. He does what is asked of him and does it to the best of his ability.
And most people here did say that Mkhi was poor in the initial 5 games, despite the assists. And apart from the game against Liverpool, he was given a decent amount of freedom. Ok sure, he was asked to track back and help the team out vs Chelsea and Spurs, but we hadn't 'parked the bus' in the 2 games. It was up to him to take the game in the direction he wanted, and all he did was lose the ball when he should have passed
The players who played yesterday excluding Mata.
He has played with 2/3 players consistently and had Lingard instead as the 3rd. If he needs that exact particular set of players to succeed, then there is no point keeping him as he can't adapt his game as per the players. Every player needs a certain condition around him to succeed- say for Mata it is pace, Lukaku it is decent service, but for none it is a particular player. And before you point towards our performances with and without Pogba, it is because he brings to the table none of our midfielders can- a good passing range along with a threat going forward.
