Toure has spoken of his sadness following the death of his brother Ibrahim and suggested that his club did not offer him sufficient support during a period which he describes as "the hardest in my life".
Speaking to France Football, Toure said: "At the end of the season, I wanted to stay for four or five days with my brother before I flew to prepare for the World Cup with Ivory Coast, except that City did not want to grant me a few days.
"I went to celebrate the title championship in Abu Dhabi while my brother was lying in his sickbed. By fortune, Kolo was at his bedside. After that I blame myself for not insisting and for not making them respect me.
"However, club officials knew very well that I was suffering for a few months as the health of my brother declined. This is the reason I had several injuries at the end of the season, because my head had taken control of my body. These last four months have probably been the hardest in my life."
