This was a terrific advert for the Champions League but it's time to say goodbye. Many thanks for your company. There's reaction from Arsenal's 2-0 home defeat to Barcelona on the BBC Sport website. Until next time...
- Juventus come from 2-0 down to draw
- Juventus seeking to reach second straight final
- Bayern last won Champions League in 2013
These two do it all over again in Bayern's Allianz Arena on 16 March. A goalless draw will be enough to send Bayern through. Juve have to score in Germany.
Bayern enjoyed two-thirds possession away to the best team in Italy but still couldn't win.
Bayern's players have gone over to applaud their travelling fans. There isn't a smile to be seen on any faces wearing red shirts. As for holding hands and performing running dives in front of them...forget it.
Terrific tie. Helter-skelter at times. Bayern will head back to Germany feeling a little flat after being in such a commanding position. Great fightback by Juventus but have they got the ammunition to bring down Pep Guardiola's men in the second leg?
Pinball inside the Juventus area before Juve just about get it away.
Three minutes of additional time. Time for a late twist in a tie oozing drama?
Martin Atkinson has had a pretty good game but he is forced to brandish another yellow in Arturo Vidal's direction after the former Juventus man after almost ripping the shirt from Alvaro Morata's back.
Bayern are finishing strongly. Franck Ribery gets beyond his man before pinging the ball across the six yard area. Juventus escape. Just.
Four minutes of normal time remaining. Arjen Robben skips past a challenge before cutting in and squaring across the six yard area. A Juventus leg just about manages to stab it clear.
No one is leaving their seat inside the Juventus Stadium. This tie has ebbed and flowed and there is still time for another late twist before the second leg in Munich in three weeks.
Juventus are doing all the pressing in the closing stages. The visitors can't clear the ball inside their area and Paul Pogba heads just over. The home fans are in full voice.
Bayern, with their two away goals, will still be favourites to advance if the score remains like this. But what a comeback by Juve. They looked down and out when Arjen Robben made it 2-0 but two goals in 13 minutes has turned the tie upside down. Can Juve get another?
Astonishing scenes in the Juventus Stadium. Substitute Stefano Sturaro stabs home an equaliser which seemed so unlikely 15 minutes ago after Alvaro Morata - another substitute - heads across goal. Bayern are on the ropes.
Juventus' second change as midfielder Sami Khedira comes off for Stefano Sturaro.
What an astonishing turnaround. Bayern Munich were bossing this so much it was starting to get embarrassing for Juventus but Dybala's goal has turned the tie on its head.
On the counter, Manuel Neuer produces a huge save to keep out Juan Cuadrado before Paul Pogna curls an effort just over.
Juve fans, silent for long periods, are roaring their team forward.
Tempera are bubbling and Martin Atkinson has his work cut out as Mario Mandzukic and Robert Lewandowski go head-to-head. Atkinson issues a stern lecture and nothing more.
Out of nowhere Juventus are back in the tie as Paulo Dybala fires his first Champions League goal of the campaign, a composed low finish, after Bayern's makeshift defence is caught out for the first time.
Great scenes in the Bayern end. Fans draped in red and white linking arms and jumping up and down on the spot. They're loving this.
Clash of the European heavyweights? This has been men against boys at times. Juventus have been bullied from start to finish. It could get very ugly for the Italians before this is finished.
Outstanding by Arjen Robben as the former Chelsea man evades two challenges on the edge of the area before rifling past Gianluigi Buffon. Juve have a mountain to climb. Robert Lewandowski with the pass to set up Robben for his sublime finish.
Juventus are struggling to string a couple of passes together. Their passing is awful compared to the zip and zest of Bayern's. It is far too easy for the Germans.
Bayern continuing to tease and torment their hosts. Arturo Vidal almost sets Robert Lewandowski free inside the Italian box before David Alaba fires just over. It's looking rather ominous for Juve.
There's a change for Juventus at the start of the second half - and it looks enforced rather than a tactical switch. Midfielder Claudio Marchisio is replaced by Brazilian Hernanes.
It's been a German masterclass in Turin so far. Can Juventus stem Bayern's tidal wave of attacks or are Pep Guardiola's men going to wrap this tie up before the second leg? We're back under way.
Former Chelsea winger on BBC Radio 5 live
"Juve have been all over the place. It was a matter of time before Bayern were going to score. They looked totally and utterly comfortable."
As you can see Bayern (right) have been camped in the Juve half. While Juve have barely left theirs. Do you think that will change after the break?
Francis Edwards: Juve being played off the park here, if there's a team to beat Barcelona then Bayern are that team, amazing stuff.
Relentless - and utterly absorbing - from Bayern Munich. A big half-time talk required from Massimiliano Allegri.
At last Bayern have the away goal their play thoroughly deserves. Thomas Muller, guilty of a glaring miss earlier, stabs home after Juventus had failed to clear Arjen Robben's cross which was pulled back by Douglas Costa.
A bullet header by Arjen Robben from a corner fizzes just wide of the post. No let up from the visitors, who will be frustrated they are not leading. Juventus, on the other hand, will no doubt take a goalless draw now.
The good news for Juventus is they have now gone more than 14 and a half hours without conceding a goal. But how long is their back line going to hold out against Bayern, who are mounting wave after wave of attacks?
