Just look at Kevin Phillips, He has almost single handedly got Palace up.
I think Murray’s 30 goals and Zaha’s creativity played a bigger part in their promotion for starters.
He did pop up with some vital goals but wheeling an old man out for 20 minutes at the end of the game is not the route I would like to see us go down.
Coyle’s team will be a lot more direct than Martinez but if he can get the balance right between keeping possession , utilising it well and sometimes knowing when it is worth a punt then I think there is enough creativity in the team to do well.
Add a steady defence and we should be on course for a decent season.
If he wants to start hitting long balls up for fun he will need to replace 90% of the squad IMO.
