You have no idea that he will transfer any form from Burnley (relegated) before he has set foot onto the pitch for nufcWhat? What logic is this?
So if a player is good somewhere else you can't make a judgement on his ability until he's played for your own team, or compare him against your current players?
you can assume he maybe an upgrade but until proven beyond doubt , that’s all it is. An assumption
thats logic for you
