Arsenal boss Arsene Wenger is reportedly eyeing moves for free agent defenders Joseph Yobo and Diego Lugano following the injury to Mathieu Debuchy.
The French international injured his ankle during the game against Manchester City and has now confirmed that he has a 'broken ligament' and will wait for further assessment to know if he has to undergo surgery to heal the injury.
The Gunners are threadbare at the back and have just Per Mertesacker and Laurent Koscielny as the recognised central defenders in the squad. 19-year-old Calum Chambers was brought in as backup, but with Debuchy out, the young Englishman will have to cover at full-back leaving the defence vulnerable.
It is now believed that Wenger is looking to bring in a defender to provide cover for the first-choice pairing and has set his eyes on one of Yobo or Lugano. Despite the transfer window being closed, clubs are allowed to sign players, who are not contracted to any club.
Both the defenders have Premier League experience, with Yobo playing for Everton and Norwich City and Lugano for West Bromwich Albion.
Meanwhile, Arsenal winger Alex Oxlade-Chamberlain, who has not been in the Gunners starting lineup off late understands that he has to fight for his place in the team. He has revealed that he is ready to do the job whenever his manager needs him.
"I feel good in myself and when I get told to play I will be chomping at the bit to help the team. It is up to the boss to decide when that is but I will be ready," Oxlade-Chamberlain said, as quoted on Arsenal's official site.
"I have been [dealing with competition for places] for four years. I know what this game is all about. I am a young lad in a very good Arsenal squad and I understand that," the England international added.
