Kylian Mbappé missed a penalty and limped off injured as Ligue 1 leaders Paris Saint-Germain battled to victory at Montpellier. The World Cup golden boot winner saw a spot-kick saved by Benjamin Lecomte before a retake was ordered and the France forward missed again. He was then forced off after just 21 minutes having suffered an injury. PSG would go on to win 3-1, with Fabián Ruiz and Lionel Messi scoring before 16-year-old Warren Zaïre-Emery made sure of victory in stoppage time after Arnaud Nordin pulled one back for the hosts. A potential injury will be of concern to Christophe Galtier, whose PSG side face Bayern Munich in the first leg of their Champions League tie on 14 February. Bayern themselves had a much more straightforward evening, beating Mainz 4-0 to reach the quarter-finals of the DFB-Pokal. João Cancelo provided an assist early on his Bayern debut, crossing for Eric Maxim Choupo-Moting to volley the visitors ahead. Jamal Musiala and Leroy Sané struck before the break to all-but settle the tie, with Alphonso Davies adding a late fourth as Alexander Hack saw red for Mainz in the closing stages. Arsenal loanee Folarin Balogun continued his fine form at Reims, with the young forward hitting a hat-trick in a 4-2 win over Lorient to take him clear of Mbappé as the top goalscorer in Ligue 1. Elsewhere, second-place Marseille moved up to second place as a João Victor own goal and a late Azzedine Ounahi strike sealed a 2-0 victory at Nantes. They displaced Lens, who slipped to third after losing 1-0 at home to Nice, for whom Gaëtan Laborde hit the game’s only goal. La Liga pace-setters Barcelona were pushed hard at Real Betis before securing a hard-fought 2-1 win. Raphinha opened the scoring after 65 minutes and Robert Lewandowski doubled the lead before a Jules Koundé own goal made the last five minutes more nervy. A late red card for Betis midfielder William Carvalho helped Barça over the line. Serie A bottom club Cremonese shocked Roma with a 2-1 win at the Stadio Olimpico to reach the Coppa Italia quarter-finals. José Mourinho’s side slipped to defeat at home as a Cyriel Dessers penalty and a Mehmet Celik own goal saw Cremonese, without a league victory all season, spring a major surprise. In the last eight they will face Fiorentina, who ran out 2-1 winners at home to Torino.
