Absolutely. Our midfield consists of too many defenders and it has for years. Midfielders need to have a grasp of attack and defence , but Barry and McCarthy excel only in defence. Gana has been a revelation this season because he's an actual midfielder who can defend and attack. Besic can also do both. We need to rebuild our midfield retaining only Gana and Davies. Hopefully Besic can return eventually as well.
For me Besic has had real glimpses of fulfilling our needs, yet they've merely been short term due to his lack of selection and his frequent injuries.
Due to that, personally I still have doubts whether he can fulfil the role we require of him - squad player yes, but first XI is still questionable.
The issue for me is the mould of player that we have shackles us offensively, dictates our whole tempo (or lack of) and ensures we're toothless.
We need someone to sit next to Gana or Barry, who I still think is elegant in his role but his legs have done, that dictates tempo and looks ahead.
Schneiderlin would be perfect as he's strong, determined, can pass well but also wants to play nice football from the centre of midfield.
Right now it's just two touch, slow football that goes from side to side in front of our opposition who then ultimately pounce and rip us a new one.
However, we then need someone in front of the midfield who can maintain this tempo, unlock defences and let our wide players move freely.
You look what Gylfi does for Swansea and he's surrounded by dross. Compared to Eriksen, Ozil, Coutinho, Mata, Silva et al we have nothing.
I feel like I am repeating myself over and over, but I think those subtle changes would change us dramatically and induce a huge improvement.
Then we could look at making the finite changes to our squad that would tweak us further, while right now we need a massive overhaul.
