Barcelona won 3-1 at Alaves in La Liga on Saturday thanks to goals by Robert Lewandowski, Ilkay Gundogan and substitute Vitor Roque, who was sent off after picking up a second yellow card.
Barcelona opened the scoring thanks to an incisive pass from Gundogan to Lewandowski and the Pole lofted the ball over goalkeeper Antonio Sivera to score his ninth goal of the season.
Gundogan popped up early in the second half with a fine left-foot strike from Pedri’s pass to increase Barcelona’s lead.
Alaves launched a quick counter-attack two minutes later following a breakaway by Alex Sola who crossed for Samu Omorodion to head home.
“We knew how to compete and we were very solid at the back. The pity is that goal we conceded, because we had the game under control at 2-0 and within minutes they scored. We defended the box badly and that makes me angry, because we worked hard,” said Barca coach Xavi Hernandez.
The Bavarians, who scored three times after Gladbach took a first-half lead, moved to 50 points in second place, two behind leaders Bayer Leverkusen ahead of their summit clash next week.
The result also earned a new record for Bayern’s veteran attacking midfielder Thomas Mueller who notched his 500th victory in all competitions for the club, the first Bayern player to reach that mark.
The visitors stunned Bayern by taking a 35th-minute lead through Nico Elvedi. The Bavarians levelled on the stroke of half-time through teenager Aleksandar Pavlovic who scored for the second week in a row.
