Koren Is our most creative player. What we seem to lack is wingers who can cross. It's alright having pace, and tricks, but at the end of the day if you've got no end product it's a waste of time. If you look at the wide players we have when we got promoted we had Hughes and Garcia, Not the fastest, Not the most skillful but both could cross. IMO if anything in the midfield needs to change it's the wide players.
That said our strikers do lack movement. Much of the time last season there was only Fryatt making the clever runs, But often ended up in positions out wide, Which is no good considering he's our only goal threat.
