Siggy is a passenger at best in most games he plays in, Carlo knows this. Do you seriously think that a manager of his ability and experience would want Siggy playing in his team every week if he had a choice? We can all see Siggy is a fish out of water, and is not viable in a squad pushing for Europe, which is our stated aim. Carlo is a World Class manager so of course he knows this.
Lack of options is one of the reasons he is playing, yes I know we let moaning Morgan go, but I imagine we had no choice but to let him go once he made it clear he wanted to go. Another reason is to preserve any semblance of fee we might get for him when he goes in the summer.
A new midfield player is a must, but once we get Gambin fit we will have Gomes, Davies, Gambin and another player. Both Davies and Gomes work best in a midfield 3 with a ball winner so maybe have 2 midfielders arrive in the window.
