VIDEO: Cavan Sullivan or Kevin De Bruyne? 14-year-old USMNT prospect - who is set to sign for Manchester City - delivers pinpoint assist for Philadelphia Union II on professional debut

The 14-year-old, who is on the verge of signing for Pep Guardiola's Manchester City, delivered the long-range assist in stupendous fashion for Union II on Sunday. The delivery landed perfectly in front of the feet of the striker, who then fired home to make it 2-1. Sullivan's pass ended up being the game-winning plug, with Union II claiming victory on the day over New England Revolution II.

Sullivan has been dubbed the "best 14-year-old in the world" by Man City scouts, and as a result, the Premier League side have worked to secure his services before he signed a first-team professional contract with the Union.

On a brilliant weekend where Cavan made his pro debut, his older brother Quinn, 19, also netted a strike for the first-team in a 3-1 victory over the Portland Timbers. Less than 24 hours later, he was pictured in the stands rooting on Cavan and Union II.

According to transfer guru Fabrizio Romano, Sullivan and City are set to put pen to paper 'soon,' with the 14-year-old joining the reigning treble-winners on a multi-year deal. Until then, though, there is a plan in place for Cavan to play with the Union U17s in the Generation Adidas tournament at the end of the month.
