If he is on contract until the summer of 2027, then that figure is way too low.
Apart from not scoring enough with his head, he is pretty much the complete striker with a powerful shot, ability to get in the right place for close range finishes, run with the ball (both attributes he showed yesterday) ability to control the ball and lay it off well, can come back and make longer passes to players running through
Other than Haaland or Isak is there any striker in the league you would have rather have? And they are well into the 125 million range. Just imagine him at Liverpool instead of Nunez. He would probably have hit 20 league goals by now
Give him at least 50,000 a week more. It might make him happy and will show other players joining that Palace reward outstanding ability
