The second-string shot-stopper commanded his area brilliantly, making a number of very important punches.
The Brazilian didn't offer width on the left-hand side and failed to whip in any dangerous balls.

The Chilean winger was perhaps brought down unfairly in the penalty area by Asenjo, but didn't look the same afterwards, seeming to struggle with two knocks.
