I don't know what wages he is on, but whatever it was he signed on in 2021 as a top bracket, will likely be lower down these days relative to other wages. Shouldn't be as much of an issue as actually clubs wanting him and wanting to pay some fee.
In the sunmer he will have two years left on his contract. But another year like the last two or three here, wouldn't be good for him or his chances of going to the world cup. It wouldn't be an issue for us though, having him around another year.
Who knows how the summer will look in fairness. Kdb almost certainly leaving, Gundo too maybe, Kovacic a possibility, Bernardo wouldn't rule it out. Depending on who comes in Grealish may be good to have around and maybe some opportunities do open up for him here. If he can get some consistency and step it up over the next 4-5 months.
