William Gallas' disputed goal five minutes from time lifted Arsenal past Hull 2-1 and into the FA Cup semifinals on Tuesday. Hull stunned Arsenal at Emirates Stadium in the 13th minute when defender Andy Dawson's lofted pass found Nick Barmby in the area and his shot deflected off Arsenal defender Johan Djourou and looped in over goalkeeper Lukasz Fabianski. The equalizer didn't arrive until the 75th, after a pass by Nicklas Bendtner in front of goal was deflected into the path of Andrei Arshavin who set up Robin van Persie for an easy tap-in. Hull goalkeeper Boaz Myhill came off his line to punch a long ball clear but it came off Djourou and Gallas won a duel with Dawson to head the ball into an empty net. But Gallas appeared to be in an offside position, according to television replays. Arsenal had several chances to equalize in the first half, mainly through Arshavin. In the 31st, the Russian playmaker's shot was palmed away by Myhill. Ten minutes later, Arshavin was alone in front of goal, but Hull defender Samuel Ricketts lunged in just in time to block his shot. In stoppage time, Arshavin blasted the ball across the face of the goal but it swerved just wide. Semifinal draw: Arsenal vs. Chelsea – April 18. Manchester United vs. Everton - April 19. Matches will be played at Wembley Stadium.
