This year I couldn't follow Man Utd, nor EPL, bar City in their last 7 matches, my two cents are that:
In City I've seen Erling (from Finland? can't recall), he worked his arse off, he has THE size, he is always going into positions with great stamina, not much of dribbling, big but not precisely a powerful shot, he seems that he can't score that much (he is really young) but he pretty much wants to be involved, he might evolved in a prolific striker but at least he works a lot as a pivot.
Another fella I must admit I watched him once in a KO in the WC, but oh boy that lad has confidence in himself and grit, he entered with the match pretty much resolved, scored from an outrageous header, created caos with his attitude and winning mentality taking no prisoners, big size, big attitude, he played for Holland and I think Man Utd should go for him,
his name is Wout sthg,
About this Lautaro, I don't follow Serie A, but what can I say it's bellow trash, like La Liga, or the Frogs League, Southhampton would win any of those Leagues.
PD: Just watched some highlights and we should keep an eye on Mitoma and Sterling, both still pretty young and the sky is the ceiling once they just improve a bit their decision making
