JERUSALEM, April 14 (Reuters) - Beitar Jerusalem owner Arkady Gaydamak condemned his own fans on Monday after a pitch invasion on the previous day denied the league leaders a probable Israeli league title. 'It's my team, not their team. They should go out from the stadium, they should go out from Beitar, they should go out from our lives. Those people are hopeless, they are insolent...and stupid,' the Russian-born billionaire said in English on Israeli Army Radio. Sunday's match against Maccabi Herzliya was called off four minutes before time with Beitar leading 1-0 after home fans spilled on to the pitch for an early celebration of back-to-back titles. Victory would have given Beitar a 15-point lead over their nearest rivals with five matches left to play. Instead, they face stiff sanctions from Israel's Football Association. A hearing is planned later this week. Last year, about 50 supporters were injured as several hundred people stormed the pitch to celebrate Beiter's impending 2007 championship.
