(AP) LONDON: Manchester United fought back at Blackpool to win 3-2 Tuesday and stay unbeaten in the Premier League, while Arsenal eliminated Ipswich to reach the League Cup final. United trailed 2-0 at halftime in its first top flight meeting with Blackpool for 40 years after Craig Cathcart and DJ Campbell scored from corners. The leaders' fightback began after Wayne Rooney was substituted. Dimitar Berbatov pulled one back in the 72nd minute and he netted again after Javier Hernandez's equalizer. United has a five-point lead over Arsenal, but the second-place team was focused Tuesday on reaching its first domestic final since 2005. The Gunners took until the 61st minute to wipe out Ipswich's 1-0 first-leg advantage in their League Cup semifinal. But after Nicklas Bendtner scored, Laurent Koscielny netted again and Cesc Fabregas secured a 3-1 aggregate win. Arsenal's Bacary Sagna was taken to hospital with concussion sustained in a clash of heads with Wojciech Szczesny, his goalkeeper. Arsenal will face West Ham or Birmingham in the Feb. 27 final. West Ham leads 2-1 going into Wednesday's second leg. Man United looked set for its first league loss since April when Cathcart, a former Old Trafford defender, headed in Charlie Adam's corner after 15 minutes. The home threat was unrelenting with United goalkeeper Edwin van der Sar having to pull off a save to block a header from his own defender, Nemanja Vidic. Blackpool went further in front in the 43rd when another corner from Adam was met by Campbell at the far post. Blackpool felt aggrieved not to be awarded a penalty at the start of the second half when Luke Varney was sent tumbling by Rafael da Silva. Berbatov began United's comeback when he tapped home from Darren Fletcher's cross. Within two minutes, a chip from substitute Ryan Giggs sent Hernandez streaking through and the Mexico striker made it 2-2. Even after United was rocked by a serious injury that saw Rafael stretchered off with apparent concussion, Paul Scholes sprayed the ball through to Berbatov and the Bulgaria striker scored his fifth goal in four days. Also Tuesday, Gabriel Agbonlahor and Ashley Young maintained Aston Villa resurgence with second-half goals that clinched a 2-1 victory over Wigan. Villa, which beat Manchester City Saturday, is six points clear of the relegation zone. James McCarthy pulled one back for Wigan, which is in the bottom three after winning just once in nine games. Palermo beats Parma Palermo beat Parma 5-4 in a penalty shootout Tuesday to advance to the Italian Cup semifinals. Daniel Martinez, a 17-year-old from Paraguay, converted the decisive penalty for Palermo after Francesco Valiani fired over for Parma. The score was 0-0 after extra time and the shootout opened with shots from Parma's Hernan Crespo and Palermo's Mattia Cassani both being blocked.
