KEY POINTS:
Substitute Toni Kroos hit a last-gasp winner as four-times European champions Bayern Munich came from behind for a 3-2 UEFA Cup win at Red Star Belgrade.
And twice-winners Tottenham Hotspur slumped to a 2-1 home loss against Getafe, prompting manager Martin Jol's sacking.
Bayern broke Red Star's hearts in the Serbian capital as the Germans, who missed out on a Champions League place, left it late to win their opening Group F tie, although manager Ottmar Hitzfeld said it was a "fortuitous win".
"Both teams played good football on a difficult pitch. We were on the back foot for long spells and they didn't deserve to lose," said Hitzfeld.
Serbia winger Ognjen Koroman had fired Red Star ahead after 16 minutes but Germany striker Miroslav Klose silenced the 45,000 home crowd with a close-range tap-in.
Bayern fell behind again on 74 minutes when midfielder Nenad Milijas beat Michael Rensing with a swerving shot from 25 metres. But Klose was left unmarked to head home in the 85th minute. After Red Star defender Milos Bajalica had been sent off in injury time for a second yellow card Kroos lashed the winner.
There were also wins for Germany's Bayern Leverkusen and Hamburg SV. The former overcame Toulouse 1-0 at home in Group E, with a first-half goal from Stefan Kiessling, while Hamburg won by the same scoreline at newly-crowned Norwegian champions Brann Bergen. Belgian defender Vincent Kompany got the only goal after an hour.
Tottenham had hoped to get a morale-boosting win in Group G at home to Primera Liga strugglers Getafe and Jermain Defoe, handed a rare start, headed Spurs in front on 19 minutes, but Ruben de la Red got the faintest of touches to midfielder Esteban Granero's freekick to beat Radek Cerny for the equaliser. Braulio finished off a superb Getafe 71st minute move, backheeling in a David Cortes cross for the winner.
Zenit St Petersburg and AZ Alkmaar shared the points in Group A after a 1-1 draw in Russia, the Dutch side holding out for the entire second half with 10 men.
Argentine teenage striker Sergio Aguero rescued a point for Atletico Madrid with a goal five minutes from time to earn a 3-3 draw with Lokomotiv Moscow in Group B. Villarreal snatched a late draw, with Joan Capdevila's 88th-minute goal, cancelling out Christian Vieri's strike for Fiorentina in Group C.
