The Daily Mail says City have lodged their interest in Barcelona right-back Alves.
The brilliant Brazilian has yet to sort out a new contract with the Spanish champions and has had his head turned by the possibility of greater riches at Eastlands.
City are in the market for the best players in the world and Alves fits the bill either at right-back or right midfield.
They are willing to pay the money required for those targets and Barcelona know they will press strongly for a deal if 27-year-old Alves shows any interest in the move.
Barca do not want to sell but they paid a massive £36m in the deal to bring Alves from Sevilla just two years ago and would expect a significant profit if pushed into a corner.
