He was really bad tonight. 2 of the goals looked very saveable. He does have these moments where he moves like a sloth. Isn't very on his toes. Watch the moments before the Dortmund keeper saves the Kenan shot onto the post to see the difference. He's too flat-footed.
I should also point out that he made a brilliant point blank save from Guirassy I think it was.
Games like these can decide the future for a keeper. The Juve #1 jersey is a heavy one. Or at least it used to be... If he's going to be a stay at home keeper that's one thing, but he can't be one that also doesn't save shots you expect from any top league keeper.
