Swansea 0-1 Wycombe: Richard Kone's goal secures surprising victory for Chairboys against Luke Williams' team in South Wales

Wycombe caused an upset in the Carabao Cup by defeating Championship side Swansea with a 1-0 victory thanks to Richard Kone's first-half goal in the second round of the competition.

Following on from their 2-0 home win at Northampton in the first round, Matt Bloomfield's League One side fully deserved the upset win as they booked their place in round three for just the third time in the club's history.

Kieran Sadlier had already missed a golden chance to put them ahead, firing wide with his left foot after going through, when five minutes before the break Kone made no mistake from close range after being teed up by Matt Butcher.

Swansea, who made eight changes from the derby draw with Cardiff on Sunday, barely threatened until manager Luke Williams made a triple substitution just before the hour mark, sending on Ben Cabango, Josh Tymon and Ronald.

And it was Ronald whose floated cross created a big chance for Florian Bianchini at the back post, but the Frenchman skewed his header back across goal.

Joe Allen and Liam Cullen were also thrown into the mix as Swansea pressed, but after Allen could only stab over following a goalmouth scramble, the visitors held on.

Williams criticises Swansea's 'lethargic attitude

Swansea's Luke Williams:

"The first half was atrocious. We improved after that, but it's still not a good performance.

"There was a lack of energy, lack of intensity, lack of aggression, and lack of quality in a disjointed performance.

"They've certainly been told they can't come out with that type of lethargic attitude."

Bloomfield: I'm immensely proud

Wycombe's Matt Bloomfield:

"We played some really good stuff in the first half and we knew we were going to have large spells without the ball. We worked hard on our shape and structure.

"We had to enjoy it when we had the ball playing against a possession-based team. We created some good chances in the first half.

"We had nine or 10 players out and we had to rotate the team. I'm immensely proud of the way the boys defended.

"We knew we'd need to be so well drilled in and out of possession and we executed it superbly. We had a lot of players missing through injury but the lads performed excellently."
