Exactly right, most footballers dont care about history, it comes down to recent success and what they can be offered.. Palace are in London, established in Premier League, exciting players (at the mo), whereas Villa have been in the Championship for 3 ish years and are in the Midlands which is nowhere near as desirable as London either.
We'll soon see whether Villa are just going to throw money around (Fulham) or if they're going to keep the core the same as it is (Bournemouth), either way, id say Palace are the more attractive club to a potential signing at this moment in time.

This thread is about Grealish and i do agree that we would have no chance of signing him now that the team he supports are in the premier league.
