FA YOUTH CUP: Swans 2 Doncaster 1
21st January
The Under-18s came from behind to secure victory over Doncaster Rovers in the FA Youth Cup and set up a fifth round tie against holders Chelsea.
The Swans found themselves behind at the interval in Llanelli as Liam Mandeville headed home from a Matthew Davies free kick.
But a stirring second-half comeback began with half an hour to play as Dylan Thomas netted a superb equaliser, before Owain Jones continued his recent good form with a fine run and finish from inside the box.
It means the Under-18s now travel to the five-time winners on Wednesday, January 28.

The Swans booked their place in the last 32 following victory over Watford back in December, while Doncaster reached this stage after beating Norwich.
But it was the hosts who started brightly and they came close to opening the scoring inside two minutes as Kyle Copp's inswinging free kick was met by Joe Rodon, but his header dropped inches wide of the far post.
After that electric start the pace of the game slowed as both sides failed to gain any real control, but it was the Swans who again carved out an opening on the half hour mark as Dan James shot straight at Jack McLaren.
However, it was Doncaster who broke the deadlock on 37 minutes as Liam Mandeville headed home a Matthew Davies free kick from six yards out.
The home side tried to get on level terms before the break as Owain Jones steered a shot goalwards after a fine run from Dan James, but McLaren saved comfortably to keep the visitors ahead.
Half time: Swans U18s 0 Doncaster U18s 1
The home side make a change at the break, as Adnan Maric replaced Jamie Latham in midfield.
And the Swans started quickly as Owain Jones saw an early effort parried away by McLaren, before the goalkeeper had to be alert just minutes later to deny Dan James from just inside the box.
But it wasn't long before the hosts were rewarded for their persistence as they drew level on the hour mark.
After a fine run from Owain Jones, the ball broke loose for Dylan Thomas on the edge of the penalty area and the midfielder curled a fine shot into the top left hand corner.
And just five minutes later the turnaround was complete as Owain Jones turned his marker on the right touchline before surging into the box and firing a low shot into the bottom corner.
The Swans continued to press for an all-important third, Stephen Fallon shooting across the face of goal and Dan James drilling an effort wide of the far post.
Then, as the game ticked into added time, the hosts survived an almighty scare as Paul McKay's cross from the right was met by Michael Carberry, but his header came back off the outside of the post.
But Swansea held on to reach the fifth round of the FA Youth Cup for the first time since 2012 where they will face holders Chelsea.
