PARIS, April 30 (Reuters) - Paris St Germain have been banned from the League Cup next season after some of their fans unfolded a racist banner during this season's League Cup final, the French League (LFP) said on Wednesday. PSG, already in the Ligue 1 relegation zone, could have been punished with a points deduction. Instead, they remain on 38 points and 18th in the 20-team top flight. The banner was briefly unfolded after the interval of the final on March 29, which PSG won 2-1 against northern club Racing Lens. It referred to a film about the life of the Ch'tis, a nickname for the people of northern France, which is breaking box offices records in France. It read: 'Paedophiles, unemployed, inbred: welcome chez les Ch'tis.' PSG are level on points with two clubs above them in the table, Lens and Toulouse, with three matches left to play.
