Arsenal manager Arsene Wenger revealed that the Gunners could be without Danny Welbeck Laurent, Koscielny, Mathieu Debuchy and Nacho Monreal against Galatasaray.
“Danny [Welbeck] has played a lot, he had a little groin problem. He could have played. I rotated a little bit because I wanted to give him a breather,” Wenger said.
“I had to respond at half-time unfortunately and it looked like he was alright. We have three or four strikers from game to game and not everybody can play.
“As Alexis [Sanchez] has played every game, he has to dig deep in every game. At some stage you have to rest the players.”
“We were a bit inexperienced at the back – we couldn’t play Koscielny or Monreal and we had Debuchy out as well.”
Theo Walcott, Jack Wilshere, Mesut Özil, Ospina, Mikel Arteta and Alexis Sanchez could also miss Arsenal’s Champions League Group D clash with Galatasaray.
