Brighton are in horrendous form, but still, probably will feel they are chasing an european spot, Villa are chasing CL spot, and Wolves trying to avoid relegation. None of these clubs will let their main strikers or Cunha go in January, unless you're talking about FIFA 25 here, nor should we still be stupid enough to offer sort of money that would make them consider it.
Cunha is also close to renewing according to reports, but if he's got ambition in him, it's probably going to be with release clause or gentlemans agreement, that Wolves will let him go in summer.
