He has 6 months (at best) left on his contract & no resale value. Please don't compare the two
Resale value means shit for us. I don't even know why people talk about resale value like it's even important. We paid 15 mil for Barkley with 6 months remaining and they are paying 30 mil not much of a difference. And while his wages are big it's still likely less than if we want to upgrade on Willian/Pedro with someone like Griezmann for example.
My take on this is we aren't remotely interested on getting such players and will fork on average guys like Zaha.
