He is the biggest Russian talent with EPL teams following him for a while now, didnt need much "finding" from Beppe. I certainly doubt he is an alternative to SMS or Pogba, if he comes, Allegri wont play him much in his first months and probably end the season with Bentancur minutes or similar, you dont transfer as a youngster from RPL and suddenly start bossing midfield for one of the elite European teams
As for Russia doing well in the WC, I doubt it, but if they do well, it'll be because of this guy and brothers Miranchuk
