He might be not physically ready to play weak in week out in the PL. And it is not clear it would be good for him to play in the championship where the type of football is very different from what City play. Who is going to replace him in the squad? Should we splash 40-50m on another midfielder while waiting Foden to mature? We can't just loan out a midfielder without a replacement. We play 2 games per week until January and probably after that too. We can't rely on all our midfielders staying fit and also on Dave to start many games.
