"what if Modric puts in a Transfer Request.. What can Levy do?"
It's simple: he'll just say "request denied, now please close the office door on your way out".
Ultimately Modric can do nothing except refuse to train or play, in which case he'll be in obvious breach of contract and so won't get paid. How many weeks would he keep that up for? Not many, I'll warrant.
Modric will squeal and shout, but the window will close and he'll just accept that he's got no good option except to knuckle down and get on with playing as best he can.
As Mabbutt points out keeping unhappy players at clubs can be disruptive in the dressing room and no manager wants a player who doesn’t want to play for the club.
