Birmingham City manager Lee Clark has expressed his delight with his team's performance during their 3-1 victory over Swansea City in the League Cup.

Goals from Dan Burn, Matt Green and Tom Adeyemi saw off the holders and fired the Blues into round four of the competition.

"I'm absolutely delighted. I think to win a game like that against the quality of opposition we're up against is very satisfying," BBC Sport quotes Clark as saying.

"Not only are Swansea the holders but I said before the game that I felt it was the hardest tie we could have got outside the so-called top six, a club that's on the up in everything that they do.

"Even though they made changes, I don't think it affects them as they've got a philosophy that runs through the club."

Wilfired Bony netted a consolation goal for Swansea in the 90th minute.
