Diaz is another City hopeful who recently appeared for Pep Guardiola’s side in the Champions League.
The Spaniard is very highly thought of at the Etihad and has found himself regularly on the fringes of Guardiola’s side.
The 18-year-old midfielder made his debut for City last year but had to wait until last month before getting another taste of first-team football.
A move to Ibrox could give the Malaga-born youngster an opportunity to play regular first-team games and push himself up the pecking order in Manchester.
Diaz already has one Spain Under-21 appearance under his belt and is likely to be farmed out on loan sooner rather than later.
