We'll give Del the final word.

That's all for us on a disappointing night for Scottish football, but we go again.

Thanks for your company, as ever. You'll get more on our dedicated Hearts and Kilmarnock club pages.

Cheerio.

Kilmarnock manager Derek McInnes tells BBC Scotland: "We said regardless of the outcome, we were immensely proud. I tried to give them real belief pre-match.

"We had to plant a seed of doubt and we did that. They had a couple of moments on transitions and we knew that's where we would be vulnerable.

"I thought Kieran O'Hara was terrific, some fantastic saves.

"We gave ourselves a chance tonight, that's the thing. I don't think they enjoyed the game."

Speaking of Copenhagen and Kilmarnock, let's see what manager Derek McInnes had to say after their European exit tonight...

Well, it's also been revamped like the Champions League and Europa League.

All teams compete in a new 36-team 'league phase', but there are six pots rather than eight.

That means there are six fixtures for Hearts against six different opponents, with Chelsea, Gent and Copenhagen, who just beat Kilmarnock over two legs, among them.

The draw takes place tomorrow at 13:30 BST.

Hearts goalkeeper Craig Gordon tells BBC Scotland: "Disappointed. I don't think we're far away. There was an opportunity there to win the tie. Having said that, I think the better team over the two legs has gone through, we didn't create enough.

"We didn't look like scoring for large spells. They've managed to get one and the better chances in the game were theirs."

On the mistakes leading to goals, Gordon said: "Everybody's responsible as a team. We've got to cut it out, we've got to stop it. We're beating ourselves more often than not.

"It's crazy stuff. I can't really understand why it's happening and in a such a short space of time.

"But we're a good enough team to bounce back and we need to do that on Sunday [against Dundee United]."

Hearts head coach Steven Naismith tells BBC Scotland: "We lacked quality in the final third, we did well to get the crowd going at the start but never had any real quality.

"Things fizzled out far too often. The game got away from us with another cheap goal, that's the story of the season so far.

"The way Plzen managed the game, defended their box and created chances showed why they are consistently in Europe.

"We were more in hope than expectation. We're not getting the quality we want. It's definitely not clicking at the moment."

Naismith adds that he is hoping Lawrence Shankland is fit to return at the weekend.

I don't think Hearts will sit in the dressing room and think they did enough to win the game.

They looked like a side that doesn't know what they are at the minute.

Ultimately, Hearts didn't do enough. Plain and simple.

Plzen were there for the taking.

It lacked any creativity and excitement as a performance from Hearts.

In six games this season, Hearts have drawn one and lost five.

In six games this season, Hearts haven't scored in four of them.

They will now drop into the Conference League, but there are issues to address for Steven Naismith.

Five defeats in a row for Hearts.

Another poor night for Steven Naismith's side.

Frustration boiling over as Frankie Kent and Gerald Taylor pick up yellow cards.

Four minutes added at Tynecastle.

Game's done.

Blair Spittal stand one up to the back post and keeper claims easily.

Boos follow from the home fans.

I haven't seen a game plan or a strategy from Hearts tonight.

Kye Rowles is in a bit of pain but he's back on his feet, gingerly, and is limping into the box for the corner, which comes to nothing.

Plzen break forward but Stephen Kingsley does well to end the dangerous attack.

'Missed opportunity' seems to be the theme of the night for Hearts.

It really does feel like that as well. Plzen have been there for the taking.
