Manchester City are willing to make AC Milan goalkeeper Gianluigi Donnarumma the game's richest transfer.

City are prepared to pay as much as £130million for Donnarumma, says Sky Italia.

The 18-year-old is top of Pep Guardiola's summer wishlist following Claudio Bravo's disastrous debut season.

City could now smash Paul Pogba's £89m world-record transfer fee to rivals Manchester United by offering anywhere between £104m and £130m for Italy international Donnarumma.

Gianluigi Buffon's 2001 transfer to Juventus from Parma for £32.6m is the current record for a goalie, reports The Sun.
