Chelsea proved they do not need the motivational magic of coach Jose Mourinho on the touchline as they clinched a place in the last four of the Champions League.

Didier Drogba headed Chelsea in front 10 minutes from time only for Paolo Guerrero and Mehmet Scholl to score in the closing stages and give Bayern something to shout about on the night.

England midfielder Frank Lampard's deflected goal gave Chelsea the lead on the half-hour but that was cancelled out on the night by Claudio Pizarro's second-half equaliser. Chelsea now meet either Liverpool or Juventus in the semi-finals.

Mourinho, who was completing his two-game touchline ban, was not there to enjoy the 6-5 aggregate triumph though. He had vacated the vast Olympic Stadium and returned to the more tranquil surroundings of the team hotel soon after the game began.

But with Mourinho absent and fitness coach Rui Faria once again donning the controversial woolly hat, the speculation over the manager's influence will doubtless surface once again.

The Londoners, knowing an early goal would really deflate Bayern's renewed hopes, began brightly with Lampard putting Drogba in the clear within the first two minutes.

However, the Ivory Coast striker was just beaten to the ball by the imposing frame of skipper Oliver Kahn in the Munich goal.

With fit-again Pizarro and Roy Makaay leading the Munich front line, Chelsea knew they could not take chances at the back and it needed a fine save from Petr Cech to prevent Pizarro's low drive from putting the Germans in front in two minutes later.

Chelsea enjoyed the better of the midfield exchanges and Bayern's crossing was frustrating the home fans with Pizarro and Makaay enjoying little service of note.

It was no surprise on the half-hour when Chelsea delivered a real body blow to Munich and put themselves three goals in front on aggregate.

Lampard, who scored twice in the opening game in London, put Chelsea in the driving seat with another deflected goal.

Lucio deflected Joe Cole's wayward shot past his own goalkeeper in the first leg and the German defender was at fault again.

Unlucky Lucio failed to get out of the way of Lampard's 20-yard strike and despite Kahn's last-ditch attempt to recover the situation, the ball cannoned off the goalkeeper's foot and into the net.

Michael Ballack, whose last-minute penalty at Stamford Bridge gave the Germans hope for the second leg, blazed a clear chance high over the crossbar in the 40th minute as Bayern finally began to create one or two openings.

Cech then pushed a long-range Bastian Schweinsteiger shot around the post as the hosts began to infiltrate the home defence.

In the 60th minute, Chelsea almost went 2-0 up on the night when Lampard's free-kick fell to Damien Duff on the edge of the six-yard box but Kahn saved superbly from point-blank range to deny him.

Chelsea paid for that miss four minutes later when Bayern equalised through Pizarro. He tucked the ball home on the goal-line after Cech had been beaten by Makaay's header.

The ball bounced off the inside of Cech's left-hand post and ran across the line for the waiting Pizarro to apply the finish.

Bayern were now in full flow knowing they still required two further goals to go through instead of the Londoners.

Chelsea then had a double escape in as many minutes when Robert Huth deflected Bixente Lizarazu's cross onto the top of Cech's crossbar in the 68th minute and Eidur Gudjohnsen cleared a Ballack header off the line seconds later.

Ten minutes from time Chelsea sealed the tie when Drogba, the scourge of home side in the first leg, rose to meet Cole's cross and glanced a header beyond Kahn and into the bottom corner.

But the Germans won the game on the night with late goals from Paolo Guerrero, who turned in a Schweinsteiger cross-shot from close range, and Mehmet Scholl added a winner which turned out to be too little, too late in aggregate terms.
