Five teams hoping to win a treble this season
Barcelona remain alive in three competitions. They are top of La Liga with 63 points, seven ahead of nearest rivals Atletico Madrid, and twelve ahead of third-placed Real Madrid.
They are also in the final of the Copa Del Rey, where they will play Valencia. They have progressed to the quarter-finals of the Champions League as well, following a big win over Lyon on Wednesday.
Over in England, both Manchester City and Manchester United can still win a treble, although the latter's hopes of a Premier League title are almost non-existent. So while both could technically win a league title, they are also both alive in the FA Cup, as well as the Champions League.
Ajax, who famously eliminated Madrid in the Champions League round of 16, can also still win a treble. They are second in their domestic league, two points behind leaders PSV. They are in the final of the Dutch cup as well, where they will face Willem II.
And finally, Porto could win three trophies this season as well. They beat Roma 4-3 on aggregate to advance to the Champions League quarter-finals, and are currently second in their domestic league, only behind leaders Benfica on goal difference. They are currently in the semi-finals of the Portuguese Cup, where they face Braga.
