Although it's probably unlikely to happen due to wages. I could see us monitoring Perez's situation as he was a target for us before he permanently joined Deportivo back in 2015 -

I think out of all the clubs he has managed, the fans and board alike here have shown the most appreciation to CH.
Thankful and lucky to have him but I believe he gets his fair share of respect from us.
Unfortunately I think Dyche would be a good appointment by Palace.
Big Sam got them more organised and playing as a unit and I believe Dyche would continue where Allardyce left off.
