I think most of us are glad really, always felt that having a healthy base of players in other top European Leagues would improve us at International level.
Part of the problem with the ‘Golden Generation’ was that players would bring domestic rivalries into the international camp, imo having players willing to go abroad is a sign of dedication and professionalism (ignoring Sancho who seems to have a problem there).
I think Arteta is unrealistic to expect him to accept this, if it was a tournament gap year he would probably be inclined to wait it out a bit longer but with the Euros around the corner I would at the very least be demanding a half season loan out if I was Ramsdale, especially now Southgate has warned him.
He has to be playing first team football this season, it was naive of Arteta to bring Raya in as clear first choice and expect Ramsdale to stay.
