Falkirk manager John McGlynn is delighted to have taken the three points against his former side.

"We were coming into the game on a high - four in a row and we had only lost one goal in the last four games," he tells BBC Scotland.

"So we were in a confident, feel-good factor mood and we got off to the best possible start.

"Our tails were up and we knew that would have a knock-on effect on Hearts, who came into the game with a lot of injuries.

"We were outstanding after that, we were so good, so clinical as well.

"Some really good goals. An absolutely outstanding performance in the first half.

"It is difficult to put two of them together, but that's difficult, but Hearts are at home and we have to anticipate them and we get off to another good start in the second.

"They changed their shape and we had to defend and thankfully we defended most things.

"Fair play to the lads, they saw it out and 5-2 - I'm biting your hand off for that."
