It was just one of those nights for poor Leverkusen. One of those they would probably have rather spent locked in their rooms at their hotel in Barcelona than take to the pitch against a Messi-led team in a murderous mood.
After having dismissed their opponents 3-1, with casual ease, in the first leg of their tie, the Catalans could even have lost 0-2 and still gone through. However, Guardiola (who has been linked with Chelsea this week), set out to score goals and his players responded.
Barcelona lined up as they always do, with Messi, Pedro and Fabregas supported by Busquets, Iniesta and Xavi. Mascherano was once again utilised as a centre back, highlighting the one real weakness in the team - the lack of quality cover for the influential Carlos Puyol.
In all honesty, the Germans came to Spain with confidence. They had just beaten Bayern Munich 2-0 in the Bundesliga to record their third straight win.
That confidence lasted only 10 minutes. A trademark Messi run, an aerial through ball from Fabregas and goalkeeper Bernd Leno was reminded he had a job to do. Pedro and Xavi then had shots too, while at the other end Lars Bender managed to trouble, momentarily, Victor Valdes.
The opening goal came on 25 minutes after Xavi fed Messi, again with an aerial through ball, for the Argentine to finish with aplomb. The Germans, to their credit, did not give up and midfielder Simon Rolfes was next to test Valdes. However, with the aggregate score at 4-1 in favour of Barcelona, it was already mission impossible for Leverkusen... and when Messi made it 2-0 on the night, fed by Iniesta... it was game over.
The second half was a pure exhibition of attacking talent, with Fabregas, Messi, Tello (who came on for Iniesta) and co. pounded away at Leverkusen's goal. Messi scored his third, fourth and fifth of the night with absolute ease, to leave Robin Dutt's boys twitching in nervousness. Meanwhile, Tello, who was making his Champions League debut(!) scored twice. The Germans did manage one goal, poor consolation though it was, through Karim Bellarabi, in injury time.
Barcelona 7 (Messi 25', 42', 49', 58', 84' and Tello 55', 62') beat Bayer Leverkusen 1 (Bellarabi 90')
