Isamila Sarr could be a nice back up winger instead of signing Benrahma. Sarr is probably the quickest player in the league, tall, strong and technically proficien ton top of that. A package we desperately need. I can see him improving upon his even momentarily not too shabby output. he could be an absolute menace coming from the bench. Other than that maybe Ben Foster as back up goalie.
Cantwell is talented but i dont think he would be useful in our system at all.
Graelish might be a "leader" on the pitch but he is a problem child off it with drink driving and all this shit. stay clear.
