They dont have to be an issue. It's up to the clubs to agree the %. His contract runs out in the summer, so can't think they'll be that bothered about recouping it all.
Just done a bit of lunchtime googling. It appears J-Patz has been playing for a team called Crown Legacy FC as well as Charlotte. I think they play in a development/reserves league.
Wright is nowhere near by everything FLs said recently. Haven't had confirmation he is even back "on the grass" yet. He's got to go through a week or so of basic movement and light running first. He's still a good 2 or 3 weeks away, I'd guess.
