Barcelona escaped making history for the wrong reasons in their quarter-final encounter against Borussia Dortmund.
The Spanish giants ran rampant at home in the first encounter as they raced into a four-goal advantage.
However, marksman Guirassy would be the man to spark a potential comeback as he dispatched with ease from the penalty spot to kick-start the second leg.
Four minutes after the interval, Guirassy would bundle in a set-piece to add a second.
Chances of a comeback would be halted as a sweeping Catalan counter was fired in by Ramy Bensebaini - into his own net.
Nonetheless, Guirassy's willingness was too much to handle as he was handed his opportunity to complete a perfect hat-trick and took it from close range.
