People often have objections, because there is a context, that can't be ignored. That context in this case is who makes way, and how much he costs.
It is just not true that that he would improve our squad. Not simplisticly. If we were a player short, and he came in, it would be true. We are not. So he replaces someone. Would he improve our squad if it meant replacing KdB? or Foden? No. Gabi Mahrez and others, potentially, not for me but open to debate. At whatbhe costs, and what alternatives that could get, would he improve our squad? Not for me if that level of money can be put to better use, particularly where improvement is needed, or will be needed soon.
