(CNN) -- Lionel Messi scored his second hat-trick in four days as titleholders Barcelona marched into the knockout stage of the European Champions League on a night of milestones for the Spanish club on Tuesday. The striker, a big favorite to win his third world player of the year award after heading the 2011 nominations before the match against Viktoria Plzen, passed a double century of goals for Barca to mark coach Josep Guardiola's 200th match in charge. The Czech champions capitulated to a 4-0 home defeat in the Group H game after having Marian Cisovsky sent off for a foul in the box on Messi, who scored the resulting penalty to open the scoring in the 24th minute with his milestone goal.
