Bayern Munich manager Pep Guardiola has no injury concerns ahead of the Champions League last-16 second leg at home to Arsenal. After missing the first leg, Franck Ribery returned to the Bayern side in the commanding 6-1 Bundesliga win over Wolfsburg on Saturday .
Arsenal will be without suspended goalkeeper Wojciech Szczesny and defender Kieran Gibbs due to a calf injury. Striker Yaya Sanogo (foot) also did not travel to Germany, but centre-half Laurent Koscielny is in contention having missed the 4-1 FA Cup win over Everton because of a hamstring problem. Teenage midfielder Isaac Hayden is also in the squad. Jack Wilshere (fractured foot) remains sidelined, as do fellow midfielders Aaron Ramsey (thigh) and Kim Kallstrom (back), and full-back Nacho Monreal (ankle). Theo Walcott and Abou Diaby remain long-term absentees.
