I would much rather mistakes happen in pre-season. As for last night I am a little concerned by Joe charging out and not getting near the ball only because he has done it several times before. I don't know if he doesn't trust the defence when either Boyata or Nasty are playing or if it is a fault that needs coaching out of him. Didn't it happen to Casillas at the world cup, but then again his career is on a downward spiral. Joe is still young and has been a great player for us, a little solid competition will do him no harm. Manuel has trust in both keepers and they are both excellent - how either of them takes to playing 15 to 16 games a season is a different matter and will tell us a lot.
