Manchester City will only sign Cristiano Ronaldo from Juventus, if manager Pep Guardiola allows Raheem Sterling to leave, according to transfer expert Gianluca Di Marzio.
Ronaldo is believed to be very keen on a move to England and wants to sign for City.
The 36-year-old is into the last 11 months of his current contract with Juve and is seeking a new challenge.
It is understood that Ronaldo might not even consider a move to Paris Saint-Germain this summer, as he wants to play under Pep Guardiola.
Juventus is ready to do a deal if City sends Gabriel Jesus as part of the deal.
However, Guardiola will only sanction a move for Ronaldo if Sterling leaves.
Sterling currently wears the no.7 shirt that Ronaldo favours for the Premier League champions.
