In his pomp Toure would have been a major coup for West Ham but barely featured for the Blues after Pep Guardiola's arrival at the Etihad and turned 35 last month.
West Ham have been busy this summer making five quality signings with the promise of more to come.
Ryan Fredericks and Jack Wilshere have arrived in what look like superb free transfer deals and they join record defender signing Issa Diop, goalkeeper Lukas Fabianski and Ukraine star Andriy Yarmolenko at the club.
That has divided West Ham fans on Twitter, here is a selection of their reactions to the reports.
