Full-time from the Liberty Stadium
A stunning second-half strike from Noah Chesmain extended Millwall U21s unbeaten run to nine games with an excellent 1-0 win at Swansea City.
Chesmain grabbed the only goal of a keenly contested Professional Development League match with just 14 minutes remaining when he unleashed a left-footed piledriver into the top corner.
Scott Fitzgerald's young charges were excellent value for their win, defending solidly as a team and attacking with flair and purpose.
Swansea called Lions keeper Tom King into action after six minutes when he saved smartly to keep out Kenji Gorre's shot.
The Lions responded and twice went close as they began to settle into their stride.
Kyron Farrell sent a left-foot strike narrowly wide of the target on 11 minutes and then Jamie Philpot's header from Dylan Casey's 17th-minute cross took a deflection and smacked the top of the bar.
At the other end Henry Jones tried his luck from distance and then saw his downward header bounce inches wide.
Millwall had the last noteworthy chance of the opening half when Philpot set up Farrell, whose 25-yarder fizzed a fraction off the mark.
The Lions looked lively straight after the restart and Alfie Pavey worked his way into a good position following a powerful run, but fired wide with 50 minutes on the clock.
Chesmain fired an early warning just past the hour mark when he won possession in midfield, surged forward and let fly with a thumping effort that keeper Oliver Davies did well to hold.
Davies was called into action again when he raced out of his goal to smother the ball at Philpot's feet just moments after Pavey had seen his stinging drive fly over the bar.
Millwall were really asking questions of the home defence now and were rewarded for their efforts after 76 minutes.
Chesmain worked the ball onto his left foot and dispatched an unstoppable shot that gave Davies no chance as it flew into the top corner.
The home side tried desperately to haul themselves level with Gorre lashing the ball wide from a central position and then keeper King producing a magnificent reflex save to deny Stephen Fallon at the death.
But these young Lions dug in and were not to be denied the maximum points their efforts deserved.
