If you would have asked me this a month ago I'd have said 20k is far to much for him
Do I think someone with 3/4 years left on their contract deserves a new one based on a good month? No
If he keeps it up for a few more months I would be very fair to give him a new one
Were you in the Richarlison thread complaining that he signed a new deal a year after joining the club? I suspect not.
