Lionel Messi outdoes even himself with semi-final masterclass

Lionel Messi's exquisite Champions League double for Barcelona against Bayern Munich was a case of history repeating itself with an added magnificent assist for Neymar to seal an emphatic 3-0 semi-final, first leg win.

With the European heavyweights locked at 0-0 in Wednesday's absorbing clash at the Nou Camp, the Argentina forward picked up a 77th-minute pass and lashed a shot into the corner past Bayern goalkeeper Manuel Neuer to put Barca 1-0 up.

Three minutes later, Messi left Bayern's Germany defender Jerome Boateng on the seat of his pants and beat Neuer with a delicate chip that sent his adoring fans packed into the giant arena into delirium.

The parallels with Barca's last-four, first leg win at Real Madrid in 2011, when Messi netted two late goals including a breathtaking second, were obvious but this time around there was more to come from the South American genius.

The match had already ticked into stoppage time when Messi sent a pass into space for Neymar and the Brazil forward raced away to make it 3-0 and virtually assure Barca of a place in June's final in Berlin.

Messi's second goal, in particular, drew effusive praise from all sides, with headlines in Thursday's sports papers dubbing him everything from a god to an extra-terrestrial.

The 27-year-old recaptured the record for Champions League goals from Real's Cristiano Ronaldo and now has 77, including a competition-best 10 in the latest edition.

"It was over in a second, it just happened like that," Messi, with typical self-effacement, told reporters when asked about his second strike.

"I imagined that Boateng would expect me to switch to my stronger (left) foot so I cut back the other way," he added.

With Messi on this kind of form, it is hard to imagine Bayern mounting a comeback in Tuesday's second leg in Munich and Barca are looking good to repeat 2009's treble of Champions League and Spanish league and Cup titles won under former coach and current Bayern boss Pep Guardiola.

Guardiola, who was making his first competitive return to the Nou Camp since taking over at the German champions, had predicted that his former protege Messi would be unstoppable and so it proved.

"Germany is a very tough place to play," Messi said. "We got a very good result but we still have to go there and we can't take anything for granted."
