I think what people want in the FA Cup and League Cup is to see a team capable of beating the given opposition. We know we're going to play our strongest sides in the league and Champions League.
I hope we see a good team against Norwich. I'm not expecting or particularly wanting to see Van Dijk and Salah play, I don't even expect them to travel. I do expect to see a team capable of beating them, though. If we were playing a league one or league two side at home, we've proven before we can beat them with academy age lads, alas we aren't playing them though, we're playing a prem side. I'd be happy to see some youth players out there, someone like Kaide Gordon perhaps, but it's about finding the balance to do the important thing, which is winning the game. I think squad players ala Minamino, Oxlade Chamberlain, Jones, Tsimikas etc play. It wouldn't be fair to see too many kids playing together without that more experienced spine in the team, and it certainly wouldn't be fair on people travelling hours to a night match at Norwich.
