It's either name Carson in the squad who is by all accounts an extremely valuable member of the squad in the dressing room which will help the starting 11 or name a kid who has even less chance than Carson of stepping on the pitch. No matter what his position, there's no scenario where a kid makes their debut today so it's even more pointless than a 3rd keeper.
It's not about that. We know any kid that isn't named Palmer won't come into the equation for minutes
The point of it is to give someone coming through a taste of the match day setup with the first team. Give them the experience for the professionalism, feeling, and atmosphere, something to keep working hard for - and what better game than a packed derby
Absolutely pointless giving it to our third keeper on his last legs
