Image source, Getty ImagesBarcelona have produced a couple of good comebacks in recent years. Back in 2010, they lost 3-1 at Sevilla in the first leg of the Super Cup but won the return leg 4-0, Lionel Messi bagging a hat-trick.
Then, in the last 16 of the 2012-13 Champions League, they beat AC Milan 4-0 in the second leg - again at the Nou Camp - after losing the first leg 2-0.
