How has he developed with Napoli? Haven't heard much about him at all in recent times since his transfer
Had a bad season, fans seem only like 60/40 that he should start over Politano, who is a decent enough overall winger but nothing special. Solid mid-table starter but would struggle in the Prem I think. Did well the year before.
Some fans think he'd shine on the left as he's right-footed and Insigne ate up all the minutes there, and that seems fine because Insigne would have suffered more playing on the right and there should be some goal-scoring upside because Lozano is a cutting in shooting winger not an insane speedster you'd expect to be best on the right while being right footed, though the elite guys overcome that fine.
He cost a lot so that might be part of it, but I think the reason to be optimistic would be that he could play on the left here and it might really help his goal threat. Numbers for Mexico are okay (15 in 58) and I think he mostly plays on his favored left there.
Basically I'd say it's a solid signing who would start over current Rashford but comfortably behind Rashford back when he was in his best form. Definitely makes sense as a bridge signing for 2-3 years if you rate our youngsters and we can sell Lozano at age 29-30 at a small loss after getting a couple solid years out of him, but think Garnacho could use a year on loan tearing up the Championship or playing for one of the sides in La Liga that should stay up but not grab Europe and are short on funds (there's at minimum 5 of these teams at least) if you don't think he'd then fancy leaving.
Was supposed to be a star, but stagnated. Kinda looks like a meh signing except that maybe playing on the left can get him to be a consistent 10 goals a league season type. 27 so age is fine but probably not gonna be a great winger at this point like many expected. Also depends on if you think Sancho should play on the left or right.
