Sarr is someone we should be going for. Out of all the top 6 we don't possess as much firepower as they do - yes right now we're functioning as a unit which is fine, but it won't stay like that. We need that rapid directness as an option (Walcott didn't cut as as Iwobi doesn't).
The thing about Sarr is he has a great temperament and is similar to Richarlison in that sense. He doesn't give up like Mane and puts himself about. He has PL experience and will probably become as versatile as Richy is. I really think we should go for it, if we have the funds and can shift Besic et al.
