It's they only way I see us improving and being more completive in midfield but we can't be sentimental if we want to be challenging for the top 6 and above, we have to be ruthless and that shouldn't just concern the midfield but all over the pitch.
January isn't the time to be buying players (too expensive), and tbh we aren't going to finish any higher then 7th so doesn't seem any point, It's interesting that you say we have a plan already in place for the summer thats very unlike Everton lol
I think you have hit the nail on the head there concerning Gylfi, he can't play in a 4-3-3 and 4-3-2-1 nullify's the system Sliva wants to play, but what can he do atm when he doesn't have the players to suit his system.
Would Bruno Fernandes offer more to the side then Gyfli, what is apparent is we need 3 midfielders that can play a variety of roles within the midfield 3 we don't seem to have too many atm which might take some time to address.
I agree with you that Gana and Gylfi need replacing for us to actually play the system that Sliva wants the team to play, Gana can't pass forward nor run with the ball and when he dies he looks like a deer in headlights, Gylfi as good as he is offensive he can't drop deep and defend he is a no10...
