Antoine Griezmann grabbed the decisive goal as Atletico Madrid hit Bayern Munich with a sucker punch to reach the Champions League final.
Griezmann tucked away Atletico’s first shot on target for the crucial away goal to cancel out Xabi Alonso’s first-half strike.
On a dramatic night with both sides missing a penalty, Robert Lewandowski put Bayern back ahead 2-1 on the night and levelled the tie 2-2 on aggregate.
But they could not find a second as Diego Simeone’s side progressed on away goals to face either Real Madrid or Manchester City in Milan at the end of the month.
Atletico led courtesy of Saul Niguez’s solo goal at the Vicente Calderon last week but Bayern had won their last 11 Champions League games in Munich. The Spaniards’ game plan was clear when goalkeeper Jan Oblak was warned about time-wasting with barely 25 minutes played.
Lewandowski had already headed a decent chance wide and was then twice denied by Oblak.
Atletico’s defence was breached when David Alaba was tripped on the edge of the area in the 31st minute. Alonso drilled his free-kick hard and low and it took a big deflection off Jose Maria Gimenez on its way into the net.
Moments later Gimenez tugged back Javi Martinez to give away a spot-kick, however Oblak read Muller’s side-footed penalty correctly, diving to his right to make a fine save.
Gimenez redeemed himself shortly before half-time with some last-ditch defending to block Muller’s cross with Lewandowski poised to apply the finish.
Nine minutes after the break when Griezmann grabbed Atletico’s crucial away goal on the counter-attack, Fernando Torres sending the France international through to whip the ball past Manuel Neuer.
Bayern now needed two goals to progress, and they got one when Lewandowski pounced from close range from Arturo Vidal’s header back across goal.
However, Atletico were awarded a controversial penalty when Torres, seemingly just outside the area, was tripped by Martinez only for the striker to see his spot-kick palmed away by Neuer. Bayern piled forward but could not find a way through in a frantic finish..
