Quality keeper. That knee injury and having to play on seemed to finish him off though. Not sure how his career went after that.
He went to Mainz after us where he was for 5 years. He had an impressive first couple of seasons by all accounts. He slipped out of the first team after that and has been a free agent for the last 3 years according to Wikipedia.
Going back to the days of arblaster and ironside, pre injury he was by far, the best keeper I've seen at oakwell. And that bombastic get Davy, ruined it for us.
Same here, time wise. I agree with you, Muller is the best goalkeeper I've ever seen play for Barnsley.
