Meaninginless friendly; he wont start in the important matches.
Form is irrelevant, if Iker is fit, he keeps for Spain in the important matches.
Reina was the best keeper in the EPL last season by a big, big distance, if it wasn't for him, Liverpool would have been relegated - yet, was never going to displace Iker.
Who cares if he lost his footing for Spain in Argeninta, playing a meaningless friendly after a long flight.
