Well it depends on where you see what position Pogba ends up as? he has a lot of the tools to be an effective 6,8 or 10, but personally I think he'll excel closer to being a no.10, like a Lampard or Yaya with 2 workhorses behind him. If you're looking for a defensive mid, Kante for 22mill looks good. If you're looking for an 8, you could see if Kroos becomes available once Real sign Pogba, and if you're looking for an attacking mid you could do worse than someone like... Isco who should become available for a reasonable fee.
Don't get me wrong, I actually like Pogba, and I think Mourinho could get the best out of him, as he really strikes me as his ideal type of midfielder but I just think the potential fee has broken the insanity point.
