There's no doubt that Vicario is a top class reactionary save maker, as he proved against the Spam, but there's an awful lot about his game that stops him being a great keeper. His inability to judge crosses, his passing ability when playing out from the back and his hysterical berating of everyone else in the team, particularly when he's fucked up make me think that giving Kinsky a run in the team would be a solid move. Maybe not right now, but in the long run.
Defence is a lot easier knowing you have a reliable, solid and calm keeper behind you, than having a bi-polar, schizoid, rainman nut job between the sticks.
