15:44 - Pep blanks Schubert...by accident
Pep Guardiola was so deep in thought as he emerged from the tunnel at the Allianz Arena on Matchday 32 that he very nearly missed out on the pre-match pleasantries with Borussia Mönchengladbach counterpart Andre Schubert. See for yourselves what happened.
15:20 - Spanish bad omen?
Bayern have lost to La Liga clubs in the semi-finals in each of the last two years, losing to Real Madrid CF in 2013/14 and FC Barcelona last season. Will it be an unwanted hat-trick?
14:58 - Pre-match press conferences
Stay with us for the pre-match pressers later - Bayern's starts at 19:00CEST, and features Pep Guardiola, Manuel Neuer and Javi Martinez. Atletico will stage theirs around 17:45CEST
14:46 - Atleti have arrived
13:38 - Boateng rallies to the cause
Following a long period out through injury, Bayern defender Jerome Boateng is ready to put body and soul on the line on Tuesday after making his long-awaited comeback in the Bundesliga at the weekend.
After the 1-1 draw with Borussia Mönchengladbach, Boateng told reporters that Bayern would "put Atletico under pressure right from the start."
11:36 - Home comforts
Bayern have gone out at the semi-final stage to Spanish opposition in each of the last two seasons, but Guardiola's troops will take plenty of encouragement from the fact that they have won all 11 of their Champions League matches at the Allianz Arena since being humbled 4-0 at home to Real Madrid CF in 2013/14. Should the Bundesliga leaders overcome Atleti, they will equal the competition record for successive home wins set by Manchester United FC between 13 September 2006 and 29 April 2008.
11:05 - Final preparations
It may be a national holiday, but Bayern cannot afford to put their feet up as they prepare for one almighty Atletico-sized hurdle. We'll be hearing from defensive specialist Javi Martinez, goalkeeper Manuel Neuer and head coach Pep Guardiola around 19:00CEST.
10:46 - Ribery concern
Franck Ribery missed out for Bayern at the weekend after suffering a back injury as a substitute at Atleti's Vicente Calderon, and Guardiola admitted in his post-match press conference that he does not know if the Frenchman will be fit to face Los Colchoneros.
10:12 - Weekend recap
Pep Guardiola made a raft of changes to the side that lost in Madrid as Bayern went in search of the win needed to wrap up a record fourth consecutive Bundesliga title on Saturday. Thomas Müller's 20th Bundesliga goal of the season set them on their way, but Borussia Mönchengladbach hit back through Andre Hahn to leave the defending champions needing a point from their final two games to get the job done. Atletico, meanwhile, warmed up for their trip to the Bavarian capital with a 1-0 win over Rayo Vallecano to keep the pressure firmly on La Liga leaders FC Barcelona.
09:30 - Good morning!
Do or die, all or nothing, win or bust: Bayern's treble hopes hinge on Tuesday's Champions League semi-final return leg with Club Atletico de Madrid. Atleti's Saul Niguez grabbed the only goal of the game in the Spanish capital last week, meaning Bayern simply have to score to have any chance of progressing to a third UCL final in five years. Stay tuned!
