Barcelona produced an impressive comeback to beat Atletico Madrid 3-1 on Tuesday and move four points clear at the top of La Liga.
Alex Baena fired Atletico ahead but Raphinha equalised for the champions before Dani Olmo and Ferran Torres slotted home to end the visitors run of 13 straight league games without defeat.
Barca might have been more comfortable had Robert Lewandowski not ballooned a first half penalty over the bar.
