On paper, if you look mid-long term at the midfield we've got
Lookman, Davies, Baningime and Onyekuru+Dowell and perhaps Walsh/Williams to come into the squad next summer.
However, at the moment on the wings we have;
Mirallas -- selfish and wants to make it all about himself and take 30 yard potshots
Lookman -- Great when we get the ball to his feet or in front of him, not when we play long ball sat back
Lennon -- An 'ok' player whose in the team to protect Kenny
Bolasie -- I wont slate him for now...but injured anyway
So, if we go for 2 wide players I think Vlasic needs to be in the side...other option would be to assess Vlasic on the left which allows baines to stay back as he cant track back quickly anymore...then we rely on Lennon to start in front of Kenny and Lookman to come in as sub?
I will say though, that I'm in agreement that Vlasic is a 10. I mentioned this a few times when we signed him that wed bought et another 10
