Victor Valdes is a polarising man—some love him, some can't stand him.
The goalkeeping role at Barcelona is different to every other club, though, and no man in the world could perform it better without a full summer of training.
In some ways, Valdes is more a last defender than a keeper. He doesn't see a lot of action due to the immense possession statistics his side totals, so concentration levels are key.
In Barca's tiki-taka system, the urge to "lump it" has been cleansed. That means, if a centre-back has no options ahead of him, he needs to go back to Valdes.
As a sweeper keeper, he's constantly on the edge of his box waiting for the ball, recycling possession well and even pulling off a few fancy lobbed passes.
His naturally advanced position puts him in a good position for counterattacks, and he saves a large percentage of one-on-ones with strikers—a trait that goes largely unnoticed, unfortunately.
