Kai, Werner and Hakim all have more assists this season than any Chelsea player. I think they are all more creative than what we have now.
For next season it depends on setup.
City and Liverpool both have 5 very offensive players but in different setup.
Liverpool 3 strikers and 2 FBs. Mane, Firmino, Salah, Robertson and TAA.
Man.City 3 strikers and 2 AMs. Sterling, Aguero, Mahrez, B.Silva, KDB.
None of Pool midfielders do much offensively just like City full backs.
With Kai, Timo, Hakim and Puli we need one more offensively oriented player to have same balance as them.
I would go with LB. So this is 5. And we have Azpi as RB (defensively oriented FB) plus I would go with Kante and Kovacic as 2 MFs behind Kai.
This is why when we play James (not good defensively) we go with Azpi as LB or 5 at the back. James-Alonso/Emerson I think we used just once this season because they are shit defensively.
