Exactly. Players like Eze become established at clubs like Palace because everyone accepts they're competing in a different pond. They can play every week, learn from mistakes and have the odd poor game without their careers being written off.
If we'd signed some of these players at 19 or 20, they probably wouldn't have played enough and fans would have been questioning the signing after a handful of average performances. Just look at some of the comments about Odobert already.
In fact, if Odobert had gone to Palace from Burnley, played regularly and developed there, we'd probably be sat here now wondering why we didn't sign him when we had the chance.
Football fans are brilliant with hindsight. We often judge the finished product and forget that a big reason these players became what they are is because they joined clubs that gave them the minutes, patience and environment to develop.
