It's hard to find any kind of rhythm when you never play.
This is exactly what happened to De Bruyne and Salah when they were at Chelsea. They went somewhere else and flourished.
I'm not saying Palmer will get anywhere near the levels of those two... because he won't... But if Brighton are interested in him, then they must believe in his talent as well.
Brighton's talent ID is top, top notch as well so it's a good metric to use when judging a players potential.
If Pep rates him, that's enough for me. Personally I'd rather not waste money on players like Michael Olise when Palmer, McAtee and Bobb will become better.
