Joao Felix once again tormented his parent club by scoring the first goal as Barcelona cruised to a 3-0 win at Atlético Madrid.
The Portuguese striker was on loan at Barcelona for only the fifth time this season, but he took his chance in the 39th minute.
Barcelona had started the game slowly before gaining momentum, although coach Xavi was sent off after expressing his anger at the referees.
Just two minutes into the second half, Robert Lewandowski doubled Barcelona’s lead with a good shot from a tight angle.
The experienced Polish striker turned playmaker and secured the victory with a perfect cross for Fermín López.
After losing their unbeaten record in the local league, Atlético got worse in the final minutes when Nahuel Molina tripped Vítor Roque and was sent off.
Barcelona are still eight points behind leaders Real Madrid, while Atlético is one point away from the top four places in the Champions League.
