Sevilla's Brazilian striker Luis Fabiano says that he's considering leaving the Primera Liga side once his contract has been terminated. The 29-year-old is looking for a new challenge after helping Los Rojiblancos qualify for the UEFA Champions League, stressing that he wants to guarantee a place in Brazil's squad for the World Cup. Premiership duo Manchester United and Manchester City have both shown interest in his services, after he scored in Sevilla's Champions League games with Unirea and Rangers. AC Milan are also believed to be among Fabiano's suitors. "I will look at other offers when my contract ends because as a footballer you must always look to profit from opportunities," he said. "I am happy in Sevilla and content with my position in the squad. "The 2010 World Cup is just around the corner and to play a part in that is a big dream of mine. "I am very grateful to Sevilla for the chances they have given me so far - they have helped me remain a part of the Brazilian team." Fabiano was about to join Milan in the close season, but the Serie A giants couldn't fulfill Sevilla's £25million buy-out clause. His current deal with the Spanish side will run out in the near future.
