His stat padding no longer hides his awful performances. Let's start with the positives. He's got a great touch, his short passing game really helps with possession retention and he moves around in tight spaces well when you want to retain the ball. He's a good if not great FK taker. Once in a blue moon he can pick out a good long pass.

Now let's face reality.

He's an enormous defensive liability. Mediocre players can bypass him with ease. We can just about cover him with Valencia, no chance with any other RB.

Mata has 0 workrate on attack and defence. Not that he's lazy, he just doesn't have the stamina to keep up an Effective press like Martial, Lingard, Valencia, Rashford, Herrera can. Even an unfit Rooney and lumbering Fellaini does better.

He doesn't provide width. That Liverpool goal aside he's never been effective down the wing. The fullback on his side either tucks in tight and makes it harder for everyone in central areas or bombs forward pinning the entire team back.

He's a surprisingly bad crosser. People complain about Darmian, Valencia and Lingard but Mata's genuinely a worse crosser than all 3

He doesn't and can't make dangerous runs. Just look how much more penetrative Lingard is.

He's 0 individual threat. He literally has not beaten a player 1v1 since he moved here.

He's only an ok finisher. For all my stat padding comments he's actually quite wasteful despite his good positioning. Much better finisher than Lingard but still pretty bad. Especially when he attempts a volley - highlight reels full of absolutely shocking efforts on goal from him.

He plays worse at 10 than RW. He's slow making passing decisions - gaps close and good runs get wasted. He's painfully one footed and takes about 5-6 touches whenever it's on the wrong foot to right himself before passing which also kills moves. More to the point he dithers so often when playing centrally and is weak so he often gets barged over and loses the ball. He doesn't have the pace to track back and recover it like Rooney and Ander can.
