I think he looks very nervous and a little bit lost.
Tosin is young and inexperienced, he came to us and get that experience, on paper you would look at Bartley and Dawson, two no nonsense defenders and say he will learn from those, add Hegazi in who can be okay, you think it would work for us, him and City.
The problem is that those defenders who you would think would be solid now look shells of the players they could be / used to be, they are being asked to play a way they clearly cant, they arent getting better at it either, there arent signs of improvement, they are infact getting worse at it and its affecting their all round game.
Tosin is getting minutes here and there in a very poor and out of form defence, as it stands he will probably go back to City a worse one than who came here as he is getting torn a new one every time he plays.
Personally for the time being i would switch to a 4 and put Dawson at right back (his performances this season have done nothing to keep him at centre half) and play Tosin and Hegazi or Bartley at centre half, with Gibbs at left back.
I have thought for ages with the players we have we should be playing a 4-3-3 anyway but if Big Dave and Jones are adamant they want to go 3-5-2 then at least tighten up until January and then buy defenders who can play the way they want.
