Sergio Aguero has handed City a major boost ahead of Monday's crucial top-of-the-table clash with Arsenal.
Kun limped off against Southampton at the end of last month and has missed the games against Hull, Stoke City, Borussia Monchengladbach and Swansea.
Though his heel injury was initially thought to be a minor issue, it caused the Argentina striker enough discomfort to render him unable to train properly for the best part of three weeks.
On Wednesday morning, he returned to normal training with the full squad ahead of one of the most important matches for the Blues so far this campaign.
Provided there is no reaction, Manuel Pellegrini will hope to have Aguero available for the trip to the Emirates Stadium.
The manager will confirm all the latest team news at this Friday's press conference.
Either way, welcome back Kun...
