A stunning strike from Allan Saint-Maximin deep into extra-time has seen Newcastle United defeat a spirited Oxford United in the FA Cup fourth-round replay on Tuesday.

The League One side came from two goals down to send the match into extra-time.

Sean Longstaff and Joelinton gave the Magpies a two-goal advantage at half-time.

Liam Kelly got one back for the hosts before Nathan Holland scored with practically the last kick of the game.

But Saint-Maximin saved Toon's blushes with a beautiful strike after 116 minutes of play.

Steve Bruce's side will face West Bromwich Albion in the fifth-round.
