After thinking for a few days, the player of the season could mean a few things.
We have been lucky to have so many players who have had good seasons, but the 2 standouts have been Palmer and Macca with Ruben just behind them - all for different reasons
Palmer has been the most consistent player
Macca has been the leading goalscorer with a phenomenal amount of goals
Ruben has been our most creative player
Nemane has been our best wing back
Baldwin has been our best central defender

If Macca had scored 20 goals I would have gone for Palmer but 40 goals plus for Macca is outrageous and why there is talk about requiring 1 million pound bids to take him away from us which no other player in any other position in this league would have clubs considering making a bid like that.
Basically goalscorers are gold dust and the biggest difference between teams doing well and not - so Macca for me
