Input: Consider Input: Question: How many people can Stamford Bridge hold at max capacity? Passage:The quarter-final draw also determined the teams' routes to the final, with Barcelona facing the prospect of meeting either Chelsea or Liverpool in the semi-finals. After a 31 win at Anfield, Chelsea qualified for the semi-finals with a 44 draw at Stamford Bridge. The semi-final first leg was played at the Camp Nou; although Barcelona enjoyed the majority of the possession, Chelsea's defence was resolute and they became the first side to keep a clean sheet in Barcelona in this season's competition, coming away with a goalless draw. Barcelona needed to avoid defeat to reach the final, but they found themselves a goal down within 10 minutes; after they failed to clear Frank Lampard's pass into the penalty area, Michael Essien fired a left-footed volley past Victor Valdes into the roof of the net. The rest of the match continued much the same as the first leg, with Barcelona retaining most of the possession. Despite this, they found themselves guilty of several fouls, while Chelsea made four unsuccessful penalty appeals during the match. Meanwhile, Dani Alves received his third yellow card of the knockout phase, ruling him out of Barcelona's next match, and Eric Abidal was given a straight red card for a foul on Nicolas Anelka as the French forward was through on goal. However, television replays after the incident showed that there was little contact between Abidal and Anelka. Norwegian referee Tom Henning vreb allowed a minimum of fourminutes of injury time at the end of the second half; in the third of those fourminutes just when it looked like Chelsea were about to secure a repeat of the 2008 final Messi played the ball across the edge of the penalty area to Andres Iniesta, who shot just past Petr Cech's outstretched hand for the away goal that would send Barcelona to the final.
