Depends what team he actually goes to. He's probably in the top 5 most marketable players in the world (which he has us to thank for) so he's worth at least £150-£175 million in my opinion.
- Real Madrid: Bale or Casemiro plus £50 million
- Barca: Can't see them willing to part with that sort of cash and beyond their staring XI there's nobody we need
- PSG: Straight swap for Mbappe
- Juve: Dybala straight swap or Chiellini plus £80 million
This is what I would like to see when he soon goes to one of those teams. Most likely destinition in my opinion is Real Madrid who will want to replace an aging Modric sooner rather than later.
