• Hearts
• Kilmarnock

Cheerio.

Kilmarnock defender Lewis Mayo tells BBC Scotland: "It's hard not to get emotional and feel despondent after that.

"It's a really hard one to take, a tough pill to swallow.

"We can't get too down about it, we've got another chance at Rugby Park. We need to stay level headed and calm."

Hearts head coach Steven Naismith tells BBC Scotland: "Commitment, attitude, discipline, belief. It was all there.

"It's a blow when you lose a goal so late but we knew it would be a tight tie. It'll be tight next week.

"It's European football, you need to stay disciplined at times then be brave on the ball. Out structure was good and we caused them problems.

"We've got to use that home advantage next week."

The Plzen players must've been watching the post-match antics at Hampden on Saturday...

Before then, however, the pair have league action to take care of.

Kilmarnock face a trip north to Aberdeen, while Hearts are at Motherwell.

Both fixtures kick off at 15:00 BST on Sunday.

The return legs back in Scotland take place next Thursday.

Kilmarnock and Copenhagen start the night at 19:00 BST before Hearts kick off at Tynecastle at 19:45.

Here's the penalty incident for Copenhagen's first goal...

David Watson took a swipe for the ball but appeared to catch Mohamed Elyounoussi on the calf.

Soft? Aye. But, like it or not, this sort of thing is a pen these days.

The Plzen players are currently doing a Rangers-esque celebration in front of their adoring fans.

Linked arm in arm, bouncing, chanting. The lot.

I would be emphasising the positives to the players if I was Steven Naismith

You wouldn't confidently say Hearts are favourites, but I see nothing there that would scare me into thinking they have a monumental task.

This Plzen side are very beatable.

A huge uphill battle for Kilmarnock now, even at Rugby Park next week.

Ouch.

A late sickener for Hearts.

Daniel Ogeyoke's 96th-minute own goal sends the Jambos back to Scotland with a first-leg defeat.

Oh my. Pavel Sulc is inches from a winner for Plzen.

He dinks the ball up and over Craig Gordon from a tight angle, but the ball drops wide.

I think it was a cross, but a nervy moment for the Hearts fans nonetheless.

Five minutes added in Denmark.

Killie don't look like creating much...

SIX minutes added.
