Although it is not certain Toure will be at training, manager Roberto Mancini has made it clear the Ivorian would be welcome despite his failed drugs test becoming common knowledge.
City officials have clarified the situation and have been informed there is no reason for Toure not to attend. Whether the 29-year-old actually takes up the offer depends upon other factors, including the potential for meetings with his legal team.
However, Toure's attendance at Saturday's 1-0 win over Wigan at Eastlands is seen as a good sign at a time when the player's mental state has been described as "not good" by Mancini.
"It is a bad moment for him," added the City boss.
Club sources are reluctant to discuss any aspect of Toure's case, preferring instead to keep their counsel ahead of what is sure to be a tense FA hearing, when the former Arsenal player could be banned for anything up to two years.
City made it clear in a statement released before Saturday's game that they found external interventions "unhelpful", including those from Arsene Wenger, even though it is widely assumed he spoke out on Friday with the permission of the former Arsenal player.
The Blues are anxious to point out disciplinary sanctions, including dismissal, have not been discussed inside the club and that it would be inappropriate to speculate until such time as the case is concluded.
