The Chelsea development squad’s patchy campaign has continued with a 2-0 defeat to Swansea City in South Wales on Saturday.

Adam King and Liam Cullen got the goals for the home side as Chelsea’s recent three-match winning revival came crashing to an end.

The Swans took a 14th-minute lead when an Aaron Lewis lung-bursting run saw the ball played to King who thrashed the ball beyond a helpless James Russell in the Chelsea goal.

Chelsea took time to get going in the match and when the chance eventually came, Isaac Christie-Davies found home keeper Gregor Zabret in inspired form. George Byers and Brandon Cooper went close to scoring for the home side late in the half but were unable to find the back of the net and add to Swansea City’s lead.

The second half started with controversy as Blues keeper Russell dropped a catch from a corner kick. The ball was said to have not crossed the line by the referee although there were strong appeals from the home side.

Chelsea remained flat in attack and captain Ruben Sammut headed a rare chance wide before Harvey St Clair fired a tame effort at Zabret.

Swansea City searched for a second goal and they got their rewards in injury time when Cullen prodded from a Jordon Garrick cross.

The Blues are back in action on Tuesday evening when they take on Portsmouth in the Checkatrade Trophy at Fratton Park, kick-off 7.45pm.
