Arsenal have been forced to put Nicklas Bendtner on an intense training regime after he returned to the club unfit for first team football, reports the Metro.
Bendtner was free to leave Arsenal in the summer but, despite interest from the likes of Crystal Palace, Hull City and SC Freiburg, was unable to secure a move.
Arsene Wenger confirmed in the last week of the transfer window that the 25-year-old would be staying at the club and would have to make himself available for selection.
But after spending the majority of last season on Juventus' bench, Bendtner has lost any sense of match-fitness - a fact compounded by a picture posted on Instagram earlier this week.
Arsenal have now advised the player's personal trainer Thomas Jorgensen to put Bendtner through his paces to get him fit in double-quick time.
The national paper is claiming that Arsenal have handed over a detailed plan for Bendtner's fitness and diet plan, having been left unimpressed by his figure when the Dane returned to pre-season training.
Jorgensen was quoted as saying: "He needs more fitness and has had a few problems, but it is not as if he needs to lose 20 kilograms."
The urgency to get Bendtner fit only increased after Arsenal's Yaya Sanogo was injured whilst on international duty for the French Under-21 side.
Arsenal have been left with just one fit striker in Olivier Giroud, knowing an injury to the Frenchman would leave them without a proven frontline man.
