Arsène Wenger faces a large injury list
Yesterday Arsenal won at Hull City 0-4, comfortably going through to the FA Cup quarter-finals although they had to play a 'replay'. The Gunners will face Watford on the weekend at the Emirates Stadium before to travel to Camp Nou to play the second leg of the Champions League last 16 round.
Despite the win against Hull, the night wasn't fully happy for Arsène Wenger. A few of his players were injured. It's the case of Mertesacker, with a cut close to the eye, Gabriel with muscular problems and Ramsey with a more serious injury. The situation of the centre of the defence is the most worrying, since the other starting centre-back, Laurent Koscielny, has got hamstring problems and his participation won't be confirmed until the very last moment to play against Barça. Wenger could have to improvise and put Callum Chambers, usually right-back, as a centre-back.
Petr Cech won't be in the goal. The Czech goalkeeper still have to wait a couple of weeks and he will be available again after the break for national team games. Therefore, David Ospina will be starting.
The young Oxlade-Chamberlain, starting in the first leg, won't be available either, so as Cazorla, Rosicky and Arteta who were already injured.
Wenger's possible starting XI: Ospina, Bellerín, Mertesacker, Koscielny (?), Monreal, Coquelin, Elneny, Alexis, Özil, Welbeck, Giroud
