Has his form dropped off since returning to play in Belgium? I remember reading that he moved to Brugge to save his career with Belgium but I'd figure with other keepers playing in top 5 leagues he might have less chances with the NT now.
No his form hasn't dropped. He played some matches with the NT before the EC's and did well. Only one capable of getting the no2 spot should be Casteels in my opinion, but not yet. Long term Vandevoordt seems to be candidate for future no1 at the moment.
