There was a flurry of goals in Wales as the Blues hit Swansea for eight without reply. George Nunn broke the deadlock after just five minutes but Chelsea were made to wait until two mintues after the restart for their next goal.

Myles Peart-Harris hit the target either side of a first goal for Joe Haigh to seal a brace after 55 minutes, and with the Blues four goals to the good the game looked beyond their visitors.

Haigh wrapped up his hat-trick on 84 minutes from close range after Dion Rankine got in on the scoring act two minutes beforehand. The final goal came two minutes from time when Lewis Bate made it eight goals on a good afternoon for Ed Brand's boys.

Perfect conditions for football saw the Chelsea get off to the best possible start in south Wales, our first chance resulted in George Nunn turning in Sam Iling-Juniors cross after being found unmarked in the Swansea box. That was Nunn's fourth goal of the season, all of them coming in the Under-18s Premier League campaign.

In a first-half where chances were at a premium, we were made to wait until the interval for a clear chance from either side. Immediately from kick-off the Blues attacked and Rankine's cross was initally poked towards goal by Peart-Harris who saw goalkeeper Tyler Evans deny him, but the stopper could only push the ball back into the danger area and our number 10, Peart-Harris, was there again - this time his effort rebounded off the underside of the bar. The danger wasn't cleared however and Xavier Simons struck against the post from 12-yards. It was a huge let off for the hosts.

Peart-Harris didn't let his head drop and opened his account a minute later. He pounced upon the loose touch of midfielder Erick Kenko and rifled a shot into the roof of the net. 2-0 Blues.

That goal seeemed to open the floodgates and the Blues looked as though they would score with every attack - just four minutes later, Haigh, this time found the net from 12-yards following Bate's through ball. That goal meant the score was 3-0 Chelsea.

There was no let up for Swansea as Peart-Harris notched his second of the afternoon, and third in as many PL starts to see the Blues four goals ahead after 55 minutes. He swept home Simons' low centre from close range and the points almost certainly looked to be returning to Cobham with Chelsea.

It should have been five but the post denied Chelsea again - Haigh some how hit the woodwork from a yard out and couldn't record his second goal after Bate pulled a cross back from the byline. The missed chance spurred the midfielder on and a quick fire double saw the 16-year-old complete his hat-trick.

The first was a contender for goal of the season - Haigh won the ball back in midfield and advanced into the box before he fired home into the far corner leaving 'keeper Evans without a chance.

Haigh's hat-trick and Chelsea's seventh was recorded after 84 minutes, Bate's inital shot was parried back into the path of the midfielder who volleyed home. Two minutes prior, winger Rankine put his name on the scoresheet in stunning fashion for our sixth - assisted by substitute James Clark, the former Cambridge United youngster arrowed an effort into the top right corner with his weaker left foot. It was a truly spectacular goal.

Our final goal came from the penalty spot and Bate finally got his goal after Simons was tripped by a Swansea defender as he raced through on goal - Moments later the referee blew the final whistle and the Blues returned to the top of the league table overtaking closest rivals Fulham who they lead by a point.

Ed Brand's boys are next in action on Wednesday 18 December as the Blues welcome Huddersfield Town to Kingsmeadow in the FA Youth Cup.
