I don't know how good he is, since I won't bullshit people that I follow other leagues.
Definitely do not know enough about him to call him 'far superior' when he has played zero minutes for us, is a young keeper and is playing in new league.
He'll get his chance, if he does well he'll get to keep his place, if he doesn't he'll get benched for a while - nothing wrong with that at all.
