For me, I think one of our biggest problems in attack has been the combination of wingers Pep uses.
We look best when we combine one slow tempo-controlling winger who is used alot for passing, and another winger who can come inside to score goals.
The best combination for that from our squad is Grealish LW and Foden RW.
I also think Alvarez LW and say Mahrez RW would work as well.
Jesus/Mahrez combination is just too slow and not enough goal scorers.
Alvarez/Foden combination has a slightly better chance but both perhaps are too eager for a goal, meaning we lose some possession patience from the wing play.
Palmer is a weird one, as I'm not fully sure what kind of winger he will develop into, currently as a very wide dribbling winger but defo has an eye for goal and is similar to Foden in that regard.
