Arsenal forward Lukas Podolski stormed out of first-team training on Wednesday after claiming he was suffering from a fresh groin injury, as frustration over the club's reluctance to let him leave north London reached boiling point.
The Daily Mirror reports that the want-away Germany international has not travelled with the Gunners squad for the New Year's Day clash against Southampton at St Mary's as he attempts to force an exit during the January transfer window.
Podolski is at a loss to explain the continually poor treatment he's received from Arsene Wenger this season, having been limited to a bit-part role at the Emirates in 2014/15.
The 29-year-old has been unable to cement his place in the team, with Wenger preferring to pick summer signings Danny Welbeck and Alexis Sanchez ahead of the likeable £100,000-a-week star.
Even after Podolski's two-goal salvo against Galatasaray in the Champions League, he was dropped back to the bench for the Premier League match that followed, and he's fallen further down the pecking order since the return of Olivier Giroud from injury.
Yaya Sanogo and Joel Campbell appear to be closer to regular action than the German, so it's understandable that he is considering his future with clubs like Inter Milan and Atletico Madrid reportedly circling.
However, Arsenal fans will be concerned at how quickly Podolski's alleged unhappiness seems to have escalated, and will hope that the fall-out will not have any negative impact on the rest of the team ahead of Thursday's important game on the south coast.
Podolski has since taken to social media to hit back at earlier reports by the Daily Mirror, denying that he stormed out of training yesterday after explaining he spent the entire session at London Colney working with the club's medical staff.
"I try not to comment on stories I see in the papers, but when I read something that questions my commitment & love for the club then I must speak up," he said.
