A deep-lying midfielder, he hangs back from play and pounces when opportunities arise.

Despite his ability to find the right moment to make his move, he could be little more than a bit part player in Korea and Japan.

Bielsa has used him sparingly - he started just two of the 18 matches in qualifying and came on once as a substitute.

But he set up crucial goals, most notably for Ariel Ortega in the win against Chile, and should prove a valuable addition to the replacements' bench.
