There's some tortuous definitions going on here about players who occupy the middle of the pitch in order to justify having so many of them:
"but he's not a defensive midfielder, he's a central midfielder...and that other player is not a central or defensive midfielder they're holding midfielders...and that other one is what I'd call a Regista...not a CM at all, but someone who occupies space...erm...in the midle of the pitch...but erm...further back, so we really dont have too many central midfielders at all".
Let's just accept it for what it is: we have 6 realistic starters chasing two berths. And if there's any kids coming through like Charsley, Grant and Walsh even remotely ready to step up they may as well just walk in and ask for a transfer now.
Wouldn't it be great if we had just two players chasing a position behind or beside Lukaku?
