Sergio Aguero has returned to training ahead of Manchester City's crucial clash with Arsenal.
The two sides face off on Monday night at The Emirates, both aiming to land a major blow over the other in the battle to win the Premier League.
If league leaders Leicester City drop points at the weekend away to Everton, then the winner of this clash could end up top of the league heading into Christmas.
Aguero has been in sensational form for City once again this season, but as in previous campaigns his momentum has been halted by injury.
The 27-year-old has 11 goals in 16 games this season, but only managed to make two starts out of six in the Champions League.
The Argentine's last game came at the end of November when he was substituted an hour into the win over Southampton.
Arsenal themselves are anxiously waiting on the fitness of their own star South American, Alexis Sanchez, who has been out with a hamstring injury.
