"We took a step back on Wednesday, but I don't want to dwell on it because we put it right today," said Cooper.

"I did see this reaction coming. I saw fire in their bellies in the training ground yesterday – both in the meeting we have with the players and the work on the training ground.

"Myself and the coaching staff said the boys looked ready and there was a really good vibe. It was about offering a little, but it didn't need much from me today.

"They were ready to put things right and they did that. I am anticipating the attitude we saw today again at QPR.

"I have said this on many occasions – I couldn't wish to work with a more professional, committed group of lads.

"Listen, we will lose games this season. You can see there were some surprise results today. Boxing Day will be the same.

"We can't let nights like Wednesday define us. It's the reactions that have to define us."

Swansea took the lead in the second minute when Yan Dhanda headed into the box before Ben Cabango's flick was drilled into the back of the net by Lowe.

Barnsley may have dominated possession but Swansea were constantly catching the Tykes cold on the counter and Adeboyejo headed the ball into the back of his own net after wicked corner from Matt Grimes.

"The pitch was more of a problem for Swansea than for us," said Tykes boss Valerien Ismael.

"We knew this before the game and it's awful to say this, but you have to accept it because it's part of the game in the Championship.

"We were very direct, but we lacked conviction. In some situations, we took the wrong decisions and put ourselves in difficult situations.

"Without big pressure from Swansea we conceded two goals. I told my guys to keep their heads up and now we have more time to recover for the next game.

"Own goals are part of the game and you have to accept it. I have to try and find a solution after this result but the most important thing today was our fatigue."
