Since I'm Dutch and I've followed him (and Ajax) for the last decade, I think I can shed some light on his performances over the last few years. Before he moved to Ajax from NEC, he was considered one of the better goalkeeping talents and was Ajax' second goalkeeper for quite a long time. But after Vermeer transferred to rivals Feyenoord, he really stepped up his game and has been the goalkeeper for the Dutch national squad for a reason. His ball distribution is quite good, can handle pressure from the opponent quite well and performed consistently up until the start of this season. The main reason why most people don't like him is that he's been very poor this season and nearly was responsable for Ajax' knock-out in de Champions League against PAOK. He's trying to play sweeper keeper, but makes a lot of mistakes in his positioning when his trying to intercept the ball out of his area. Besides that, his penalty-record is simply awful; he has never stopped a penalty kick in his entire professional career! So in conclusion; don't expect a world class goalkeeper, but he's a decent back-up for Ter Stegen. Would Diego Alves be better? Hell yes. Would Reina be better? Sure. But is he as awful as some people make him out to be? No. He's decent.
