#3 Barcelona have the Champions League to worry about
Barcelona's splendid season till this point puts them in a small group of clubs who are still in the running to win a treble this season. If achieved, this would give the club the unique distinction of having performed this feat on three occasions.
In the Champions League quarterfinal, the five-time champions have been paired with Manchester United and that is sure to take a higher priority on the club's scale of preference than the clash with Atletico Madrid.
It is no hidden secret that Barcelona have struggled in the continental competition in recent years, failing to make it past the last eight in four of the last five tournaments. This shortcoming is one which the Catalans would be keen to address, especially given as each of those tournaments were won by arch-rivals Real Madrid.
Barcelona would enter the clash against Atletico Madrid with one eye on their mid-week fixture with Manchester United and given this level of distraction, Atletico Madrid could capitalize on this to post a victory.
