I don't think any of the players we have are ideal for that role
We miss Pienaar - given that Baines is back now, his delivery and intelligence on the left need someone in front of him to play off. Pienaar always provided that and that's a big part of the reason that we've seen the likes of Naismith, Osman, Barkley, etc played there at times IMO
Cleverley might end up doing that role, but I see him as more of a long-term replacement for Osman really.
I also don't see Yarmolenko as that player, so it's the one position at the club that still needs to be addressed for me. Kone has done well (mostly at home) in an unusual floating position from the left, but for me we now need to set up to enable us to get the best out of Baines on the left - our left side has been, from an attacking POV, very weak this season and we've been fortunate that our right hand side has been devastating enough to take the pressure off.
Truthfully, I don't know who the answer is, but I think that left-sided role is what Roberto had in mind when he talked about that mythical "number 10" in the summer. I think we still need that one player.
