Saw this with regard to passing' ability of Deano.
Essentially, even compared to De Gea (an okay but not more than that passer), Deano compares quite weakly. He has twice the number of long passes compared to De Gea, but only half the accuracy. Perhaps more worryingly, he has only a quarter of short passes. Taking these stats together, it means that he hoofs the ball much more than he should, and he is pretty bad at it.
On the other side, he has been impressive at shot-stopping this season (has outperformed xG for 8.1 compared to De Gea doing it for only 0.2), and is better than De Gea on the air. But for people who want us to see playing from the back and having a sweeper-keeper, Deano is gonna disappoint really badly, considering that he is far worse than De Gea at it (and De Gea is not good on the first place).
So, if Ole wants to play from the back, maybe Deano is not the answer. Is Onana still good (I remember him getting praised here last year)?
In any case, maybe he deserves a chance before we splash the cash in a new keeper. I was more to give Romero the next season (with De Gea being backup trying to get his position back), but we can try the same with Deano. If De Gea manages to get back his position on merit, then we profit. If Deano impresses then we profit. If neither happens, sell both of them next summer, and get Onana (or something of that calibre).
