He hasn't missed the boat because he already had a move to a big club and didn't take the opportunity, for whatever reason. I think his head isn't quite in the right place, he knows he is running out of time to win things and probably won't at Palace, but also that he's a bit stuck.

I don't think Palace are really worried about the fee they might get, they know that even a disinterested Zaha will probably keep us in the Premier League so really don't want to sell, hence the price will stay high. We won't get the fee we would need to come close to replacing him with his current form, so he may need to get his head right for next season, or he will continue to miss out.

None of those 3 players you mention played for Palace under Tony Pulis.
We had Puncheon and Bollasie on the wings and Jedi and KG in centre midfield when he was manager.

Van Aanholt should stay up on the wings well away from our defence and Riedewald can replace him simply because he can pass, Zaha needs to go ..Van Aanholt can actually put in a decent cross.

I was really hoping we subbed Townsend on for zaha at half time.
Zaha does not cross so what's the point of having benteke on with him?

Nobody it seems can get Zaha to side-foot the ball into an empty net from 2 yards, or even trouble the goalkeeper.

He has Tekkers disease.

How they ever loaned out Wickham is beyond me, and they can't get him back.

Some might argue they were even worse than that!
But we did have a single effort on target.
