And on that note shall we say goodnight?

There is remarkably no top-flight action on Friday night so we shall be back on Saturday with Leicester v Liverpool to get your teeth into at lunchtime.

See you there!

Barnsley boss Valerien Ismael to BBC Sport: "It's exactly the game we wanted, we made a great performance. We could see how far we can bring our principles, to make Chelsea make mistakes, we did it perfect in the first half but we had to score.

"It was a change in the second half, Chelsea made a change of shape and had more control. We were punished for one moment which was a shame. But we kept fighting to the end, we are proud of the performance.

"We know that we can compete at that level. Chelsea could have had a penalty, the goal could have been offside, they are 50/50. Tonight we go to bed with a good feeling."

Chelsea

Chelsea boss Thomas Tuchel: "We changed to a back four and took Marcos [Alonso] out for this tactical change. Andreas [Christensen] had to go out because he had a headache. The changes made it a little easier to get into the opponent's half and overcome the first press.

"We did it well at the start of the second half and played constantly in the opponent's half.

"We scored the goal and I had the feeling that they increased the risk but we stepped down in the little decisions. Not enough courage and it was too deep for a long, long time.

"We clearly can play better, so yes I expected more but not in terms that I am frustrated.

"If you lack a rhythm and a bit of self-confidence and you have to show on this pitch, against an opponent that takes all the risk and plays the game of his life, that is not easy. We can do better but I don’t want to be too hard on the players."

On playing Sheffield United in the last eight: "It’s going to be a tough one. They are a very physical team that presses high. They are organised but I am happy to have a home game. This is what we wanted."

The lights just went out as Barnsley boss Valerien Ismael faced the BBC cameras. Classic.

Chelsea

Chelsea forward Tammy Abraham speaking to BBC Sport: "Coming here is never easy. Give credit to them they are a good side. I knew chances would come eventually I just had to be in the right place at the right time."

On possible penalties: "The first one was a good tackle to be fair, I tried to get my body in the way but he got the ball. The second one maybe. I just had to stay patient for the goal.

“I grew up being a defender so it was instinctive reactions and being in the right place. I saw the ball coming and had to do something and it worked."

Since – and including – the year 2000, Chelsea have reached the FA Cup quarter-final more times than any other side, with victory tonight ensuring their 15th appearance in the last eight in that time.

Barnsley can get a lot of plaudits and a pat on the back. They played ever so well. They asked a lot of questions of a Chelsea team that had made changes but still had a lot of internationals.

I don't think the Chelsea manager will be pleased. I am sure he will have words. Some players will not be playing the next game, I am sure.

Chelsea will be relieved. It was a fantastic goal, but Barnsley can hold their heads high because they did really well.

Barnsley gave it a right good go. They did really well, worked hard and created chances - their regret is they didn't take their good chances.

Since the start of last season, Tammy Abraham has scored 30 goals for Chelsea in all competitions, at least 11 more than any other player at the club.

Everton v Manchester City

Bournemouth v Southampton

Leicester City v Manchester United

Chelsea v Sheffield United

Thomas Tuchel trudges away, his side were better in the second half but they weren't exactly scintillating.

Chelsea are through and will face Sheffield United in the quarters.

Ahh, the ref gives a foul for a push. Soft.

Another free-kick for the hosts. KEEPER UP!

THREE minutes added on...

Another free-kick, Cauley Woodrow heads it on but that's easy for Kepa. Nice high line from Chelsea there.

Thomas Tuchel is restless as Barnsley win a flurry of free-kicks. The Championship side have really tested the big guns tonight.
