To me their arguments fall on deaf ears. I think the reality is they don't want roster expansion because it allows countries with some guys who are quite questionable health wise to get selected. And England would just as soon not have to potentially face those guys.
The problem with Southgate's 'pitch" about too many players and hard to manage is garbage. Nothing says you HAVE to roster 25 is they do expand it. If you are happy with 23 and think its better for your side then fine just roster 23.
