LONDON, Feb 23: Bayern Munich and Liverpool, seemingly coasting to 3-0 victories in the Champions League on Tuesday, were hit by late goals that could seriously damage their progress to the quarterfinals in two weeks' time.

Liverpool, 3-0 up against Bayer Leverkusen at Anfield, conceded a sloppy goal after a mistake by keeper Jerzy Dudek three minutes into stoppage time to give the Germans hope.

In a mirror image of what happened at an field, Bayern Munich were leading 3-0 against Arsenal in the other Anglo-German clash with time almost up when Kolo Toure pulled one back for the English champions with just a minute left of normal time. Now, instead of facing almost impossible tasks, Leverkusen and Arsenal would go through to the last eight with 2-0 wins in their home legs.

Tuesday's other first knockout round, first leg matches also ended in home wins with PSV Eindhoven beating last season's losing finalists AS Monaco 1-0 and Real Madrid defeating Juventus by the same score at the Santiago Bernabeu stadium.

A first half header from Ivan Helguera gave Real victory over their old Italian rivals but Raul, bidding to become the first player to score 50 goals in European competition, just missed out when he hit the bar in the first half.

That tie is finely balanced, as is the one between PSV and Monaco, settled by an eighth minute header from the Eindhoven side's Brazilian centre back Alex. Bayern Munich scored the first Champions League goal with the competition resuming after the winter break with just four minutes played at the Olympic Stadium.

Claudio Pizarro scored it by volleying a low shot past Arsenal's German goalkeeper Jens Lehmann after a mistake by defender Kolo Toure, who headed a long clearance from Lehmann's national team rival Oliver Kahn straight into Pizarro's path.

The Peruvian headed Bayern 2-0 ahead after 58 minutes before Arsenal's defence crumbled six minutes later allowing Bosnian midfielder Hasan Salihamidzic to pick his spot for the third.

Bayern had the chance of a fourth goal ruled out by an offside decision but, with the game comfortably won and a place in the quarter-finals beckoning, some sloppy defending allowed Arsenal back into the tie.

Patrick Vieira, who had an unimpressive game by his high standards, struck a post from close range but Bayern failed to clear and Toure, making up for his early mistake, rifled the ball home. Liverpool were similarly in command at Anfield against Leverkusen, despite being hampered by the absence of their suspended skipper Steven Gerrard.

Spaniard Luis Garcia put the home side ahead after only 15 minutes before free kicks from Norwegian John Arne Riise (35th) and German Dietmar Hamann (90+2) appeared to wrap up an emphatic victory. But with just a minute of stoppage time left, Dudek failed to collect a shot from Dimitar Berbatov and Brazilian substitute Franca lashed the ball home from close range to totally change the complexion of the tie.

A crowd of 72,500 fans at the Bernabeu stadium watched the latest instalment in the 43-year-old rivalry between Real Madrid and Juventus, which ended in a slender win for the home side.

Helguera scored the only goal, heading home a 31st minute free-kick from England skipper David Beckham. Real dominated from start to finish but one goal may not be enough to guarantee their safe passage to the next round in two weeks' time.

The first knockout stage continues on Wednesday when Barcelona host Chelsea, Manchester United welcome AC Milan, Werder Bremen entertain Olympique Lyon and European champions Porto take on visitors Inter Milan.
