Barcelona reached the UEFA Champions League quarter-finals upon outclassing Stuttgart 4-0 at Nou Camp on Tuesday. In-form forward Lionel Messi broke the deadlock after 13 minutes with a precise shot from outside the area, following an impressive run. Nine minutes later, the Argentine ace sent a defense-splitting curling pass to Yaya Toure who flicked the ball to Pedro Rodriguez, and the Spanish hitman made no mistake from close range. Virtuoso Messi netted the third goal on the hour upon rounding his marker seeing his low effort hit the bottom corner of the net. Bojan Krkic was sent in as a substitute in the dying minutes, and his introduction paid off in no time. The 19-year-old latched onto a Zlatan Ibrahimovic through pass to go one-one-one with Jens Lehmann and slide past him with aplomb one minute from time. The first leg between Barca and Stuttgart ended in a 1-1 draw in Germany, which makes the aggregate result 5-1 for the Catalans. First goal Second goal Third goal
