Leicester City: The 606 Story is starting on BBC Radio 5 live right now.

Steve Walsh, Muzzy Izzet and Alan Birchenall - each a former Fox - will be joining Mark Chapman to reflect and rejoice in the opulent surroundings of a Leicester pub. 

How do Leicester get ready for the Champions League?

Parth Mehta: No need to do anything to the squad. All Leicester need to do is be more hungry, dream more and believe.

Nouman Nisar: A replica of 13 players that they have. You cannot play 60 matches with 13 players.

Toniwater: Leicester need three old heads if they're to do anything in the Champions League. Lads with euro experience who know how to win and close out games eg Maxwell.

Atletico have won 13 of their 17 home Champions League games under Diego Simeone, drawing three and losing one.

Atletico have scored against 23 of the 25 teams they have faced this season in all competitions, only failing to score against Villarreal and PSV Eindhoven.

For a second, concurrent chat topic tonight, let's think Champions League from a purely Leicester angle.

What do they need to do to the squad to get ready for the big cup competition?

What sort of player should they target? Do they risk upsetting the close-knit team spirit to bring in 'big' names?

While Bayern are on the brink of winning their fourth successive Bundesliga title, Atletico remain firmly in the hunt in La Liga.

Diego Simeone's side are level on points with leaders Barcelona with two matches of the domestic league season remaining.

Former Liverpool forward Fernando Torres said the team are reaping the rewards of their work ethic and unity, while channeling some Pat Benatar.

"We die for each other," said the 32-year-old, a Champions League winner with Chelsea in 2012. "It's a battlefield out there.

"We are going out to win. We live the excitement of playing match by match and the situation we are in."

Big boost for Atletico - defensive linchpin Diego Godin returns at centre-half after injury. The Uruguay international replaces ex-Manchester City man Stefan Savic in an otherwise unchanged team from the first leg.

Atletico XI: Oblak, Juanfran, Godin, Gimenez, Filipe Luis, Augusto, Gabi, Koke, Saul, Griezmann, Torres.

After being left out for the first leg, Germany forward Thomas Muller starts for Bayern Munich.

All the rest of the big guns come back - Philipp Lahm, Xabi Alonso and Robert Lewandowski to name three - after they were rested for Saturday's home draw against Borussia Monchengladbach.

Bayern XI: Neuer, Lahm, Martinez, Boateng, Alaba, Ribery, Costa, Alonso,  Vidal, Müller, Lewandowski.

Johnny Magrinho: Atleti are like a wasp at a picnic - no matter how many times you swat them, they always come back. And they're hungry for jam.  

Attack v defence? It could be tonight.

But who do we expect to get through? And which of these two sides is more likely to win the Champions League in Milan in a few weeks?

You may be sick of hearing about it already - what's wrong with you?! - or you may never grow tired of reading those five words.

An extraordinary thing has happened over the past nine months and we will continue to talk about it for plenty longer yet.

If you want to chip in this evening, please do.

After all, Leicester will be in this competition next season...

Melton Mowbray has never known a party like it. Not since the first baker joined pastry with pork, anyway. I'm pretty sure that's true.

Heads will be banging, offices will be empty and hearts will be overflowing in the Leicestershire town after Jamie Vardy's epic house party to celebrate Leicester's title win last night.

Atletico are known as a defensive side but manager Diego Simeone says his side will not sit back tonight.

Atletico arrived in Germany with a 1-0 advantage after Saul Niguez's first-leg goal at the Vicente Calderon.

Simeone said Atletico will look to kill off Bayern by scoring an away goal instead of trying to play for a 0-0 draw, which would take them through.

"I'm only interested in winning," he said. "That is what I prepare for."

While Bayern are five-time European champions, Atletico are trying to win the competition for the first time.

"We are going to be true to our style," said Simeone. "We will be ourselves.

"Whatever happens will depend on the mental strength of both teams.

"In the first leg we played in a way that feels good for us. On Tuesday we will see how strong both Bayern and we are."

So what do Bayern have to do tonight? In short, a 2-0 victory will do the job.

After last week's 1-0 defeat at the Vicente Calderon, Pep's men know that is the minimum requirement to stand any chance of going through inside 90 minutes. Although that all changes if Atletico score an away goal...

And here's a stat to worry even the most confident Bayern fans - Atletico have not been beaten by a two-goal margin, in any competition, since February 2015. Gulp.
