Bayern Munich's hopes of adding a UEFA Cup title to a likely league and cup double were dented Thursday when they were held to a 1-1 draw by Zenit St Petersburg in the first leg of their semi-final in Munich.
The German league leaders got the early goal they wanted through Franck Ribery but the Russian champions threw off first-half caution to equalize when Lucio headed the ball into his own net on the hour.
Bayern were missing the suspended Luca Toni, but the Italian was barely missed in the open stages when early pressure was rewarded with an 18th-minute goal, the dpa reported.
Ze Roberto was brought down in the area by the outstretched leg of Fernando Ricken and referee Lubos Michel pointed to the spot.
Ribery shot weakly with his right foot straight to Vyacheslav Malafeev but the keeper could only parry the ball which bounced back for the midfielder to convert with his left foot.
Zenit had enjoyed a 4-1 win at Bayer Leverkusen in the previous round and Bayern coach Ottmar Hitzfeld had warned of their counter-attacking threat.
But the Russian champions appeared unwilling to commit players forward, and it was not until mid-way through the first half that Konstantin Zyryanov tested Oliver Kahn.
Bayern threatened to increase the lead, with Ze Roberto hitting the ball over the advancing Malafeev and wide of the goal, and Bastian Schweinsteiger twice shooting at the keeper.
Lukas Podolski came in for Toni to partner Miroslav Klose, who shrugged off a foot injury but struggled to make an impression
Midfielder Mark van Bommel also felt sufficiently assured to play with a broken nose suffered in Saturday's German Cup victory in extra-time over Borussia Dortmund.
Bayern, in the hunt for a second UEFA Cup crown to go with what looks a certain Bundesliga title, were warned after the break by a Viktor Fayzulin effort past the post.
With Zenit beginning to combine well in midfield, Fayzulin again found space down the left to zip in a cross which Lucio could only head past Kahn into his own net.
It was virtually the last action for 38-year-old Kahn who had minutes earlier needed treatment to a thigh strain.
Appearing in his last European match in Munich before retiring at the end of the season, he trudged off in the 66th minute to be replaced by Michael Rensing in goal.
Bayern kept pushing for a second goal and Lucio came close to making amends with a piledriver which Malafeev tipped over the bar. Zenit almost snatched a winner when Fyazulin poked the ball through Rensing's legs only to see Ze Roberto clear off the line, and Andrey Arshavin fired successively over the bar and wide of the post in the remaining minutes.
Podolski then came close to settling it with a shot narrowly wide of the post, leaving Zenit coach Dick Advocaat satisfied with the result going into the return leg at home next Thursday.
