BERLIN, May 3 (Xinhua) -- Michael Olise scored deep into stoppage time as Bayern Munich claimed a 3-3 home draw against bottom side Heidenheim on Saturday, after twice coming from two goals down.

Rotating heavily between the two legs of its Champions League semifinal against Paris Saint-Germain, Bayern fell 2-0 behind by the 31st minute. Budu Zivzivadze diverted in Marnon Busch's cross for the opener, before Eren Dinkci raced onto another Busch ball to double the lead. Leon Goretzka pulled one back with a direct free-kick just before the break.

Vincent Kompany responded at halftime by introducing Harry Kane, Olise, Luis Diaz and Joshua Kimmich, and Goretzka leveled from close range in the 57th minute after an Olise corner. Kimmich then hit the post from distance, but Zivzivadze struck again on the counter in the 76th minute to make it 3-2.

Heidenheim held out until the 100th minute, when Olise's shot came back off the post, rebounded off goalkeeper Diant Ramaj's back and trickled over the line. Bayern now turns its focus back to hosting PSG before visiting Wolfsburg, while Heidenheim remains bottom on 23 points, behind Wolfsburg on 25 and St. Pauli on 26.

"It was about mentality, about belief. Of course there are many things we can do better. We have to take that into the next match," said Kompany.

Elsewhere, Patrik Schick scored a hat-trick as Bayer Leverkusen overpowered Leipzig 4-1 to move into fourth place, while 10-man Stuttgart held Hoffenheim to a 3-3 draw. Hamburger SV came from behind to claim a vital 2-1 win in its relegation battle, Werder Bremen fell 3-1 to FC Augsburg, and Union Berlin fought back from two goals down to share the spoils with Cologne. ■
