Manchester City attacking midfielder Samir Nasri has been ruled out for up to six months following surgery on a hamstring injury.
The problem has kept the former France international out of action for over a month, with his last appearance for the club coming in the 5-1 victory over Bournemouth on October 17.
The 28-year-old has been an integral part of the City squad since moving to the Etihad Stadium from Arsenal in 2011 and he has won two Premier League titles and a League Cup crown during his time in Manchester.
Nasri, who has only started one league match so far this campaign, confirmed the news of his long injury lay-off on social media, although he admitted that he is hopeful of making a first-team return before the end of the season.
He said: “Just had surgery everything went really well hopefully will be back in 4 to 6 months.”
The news is another set-back to Manuel Pellegrini’s side, who have already had to deal without the likes of Sergio Aguero and David Silva over various parts of the season.
City have also slipped off the top of the table in recent weeks after only picking up just one point from their last two games and they face a difficult trip to Turin on Wednesday to take on Italian giants Juventus in the Champions League.
The Sky Blues have already booked their place in the knockout stages of Europe’s premier club competition and they are available at 3.40 to secure victory in Italy and seal top spot in the group, while Juve are available at 2.15 and a draw is 3.25.
