AFC Bournemouth have signed Christian Atsu from Chelsea on a season-long loan deal.
Midfielder Miguel Pallardo has signed a new one-year deal with newly-promoted Hearts while Danny Wilson leaves.
The Ivory Coast international has become a hugely influential figure in Roberto Mancini's side since arriving from Barcelona in the summer of 2010.
He may not yet have reproduced his scintillating form of last season but the 29-year-old stressed he still has more improvements to make.
"I would love to end my career here," said Toure.
"Nobody knows what the next step is in football and I believe that if you stop dreaming, you should stop playing football, but this is where I want to be.
"When I first arrived at City every time I went to sleep I would dream about us winning something and about us being the best team in whatever competition we take part in.
"I believe I have to work harder all the time to improve and stay at the top level with this club.
"I will give my all every time I play and I will never forget how the fans have treated me here so nothing would give me greater pleasure than to finish my career as a Manchester City player.
"There is no other place I would rather finish with and I want to continue winning titles and trophies with City."
City won their first top-flight championship for 44 years in a dramatic end to last season but Toure believes that will be just the beginning of a new golden era for the club.
"I believe we are just at the beginning of our journey," he told mcfc.co.uk
"We want to make history and that was part of my plan when I first signed - to make history - and we've made a start but there is so many more chapters to be written.
"I'm really enjoying my football here and I'm playing in front of the most amazing fans I've ever come across.
"Ending my playing career at City would be unbelievable, but I know it won't be easy because we want to win everything and the club is always looking to improve."
