Great news for Maidenhead. It sounds like they've had to reduce their sell on clause to get the deal over the line, and it will be paid in installments, but invested correctly this should be transformational for the club.
Great deal for Wolves. They could reinvest half that money in a left footed defender like Jacob Grieves and people will be having a debate over whose the better defender in two or so years time.
Great deal for the player. He gets to move closer to home, plays for a big club with big ambitions at a big stadium, and doesn't have to worry about his next move or finances until he hits retirement age.
The only people this deal doesn't feel great for is West Ham. Albeit they're probably not thinking about the fee and think this is a way of ensuring they hit their English quota in a position that's historically been difficult to recruit in for the foreseeable future regardless of where the club fluctuates in the English pyramid. If he makes over 200 appearances and he's fairly consistent, they're probably not going to be about this fee in 2031.
