Need to find his role and fast.
Even when he's in position, he's making mistakes. Mitoma got past him multiple times after he came on as a substitute. Straight up 1 on 1 defending, and Trent was second best.
After Ali saved Welbeck's header, Trent was in position to clear but miskicked it straight into the air, allowing Brighton to keep the pressure on.
Even when he's positioned well, he's still not defending well at all.
