Valencia:Valencia advanced to the quarterfinals of the Champions League on away goals on Tuesday after holding Inter Milan to a 0-0 draw in the second leg of the second round. Valencia advanced with two away goals after its 2-2 draw at the San Siro two weeks ago. As the whistle blew, Inter midfielder Nicolas Burdisso attacked Valencia defender Carlos Marchena, sparking clashes between the two sets of players. Valencia substitute David Navarro entered the field and punched Burdisso. Several Inter players, including Maicon, then aimed kicks at Navarro as he fled the scene. Inter coach Roberto Mancini said that Burdisso broke his nose in the brawl. The trouble continued in the tunnel with security staff preventing further clashes between the players. "It was a very tense game. It was all very ugly but it sometimes happens," Valencia sports director Amedeo Carboni said. "In half an hour they'll all be leaving together." On field brawl Six yellow cards were given out in the match and both teams made hard challenges in the final minutes, leading to the late pushing. Zlatan Ibrahimovic had Inter's only shot on goal in the first half in the eighth minute, but Valencia goalkeeper Santiago Canizares saved the weak roller from 30 meters (yards) easily. Having only to defend its lead to advance, Valencia looked more like the team in need of goal as it created the better chances early. In the ninth minute, Miguel Angel Angulo found David Villa in the middle of the area with his cross from the right, but the Spain striker muffled his shot. Fernando Morientes volleyed the rebound, but his shot was blocked. Two minutes later, midfielder Ruben Baraja stepped past Dejan Stankovic onto the edge of the area to send a low-angled shot that Inter goalkeeper Julio Cesar dived to push wide of goal. With few chances to show for 30 minutes of play, Inter's frustration started to show as Ibrahimovic was carded for a rough tackle on defender Raul Albiol. Canizares was subsequently cautioned for rushing out of his goal to voice his displeasure at Ibrahimovic. Albiol kept the Italian team scoreless six minutes later by blocking a dangerous cross sent in by Stankovic in front of his goal line. Seven minutes after the start of the second half, Olivier Dacourt beat his marker along the right before sending a cross that Stankovic stabbed wide into the side netting. Two minutes later, Cesar parried Valencia left back Emiliano Moretti's strong header from the edge of the penalty box to deny the hosts the lead. Inter saw another chance cleared off the line in the 75th, as Marchena deflected substitute Julio Ricardo Cruz's header into the arms of Canizares. With Inter pressing, the Valencia defense was busy and three minutes later Albiol's sliding tackle from behind on Cruz inside the area kept the Argentine from going in alone on Canizares. Inter couldn't find the away goal as Valencia blocked several shots within the area. In the last two meetings over two legs between the clubs - in the 2003 Champions League and the 2002 UEFA Cup - Inter advanced both times.
