Arsenal have submitted their Champions League squad for the knockout stages and to much surprise, striker Yaya Sanogo has made the cut.
Sanogo hasn't played a competitive fixture since April due to injury, when he was on loan for Charlton, but Arsene Wenger has added him to the squad.
Speaking after Arsenal's EFL Cup defeat by Southampton at the end of November, Wenger says he couldn't explain Sanogo's latest injury as the details were 'confidential'.
'He had a real medical problem that I cannot explain to you here because it is a confidential problem,' Wenger told the Daily Mirror.
