DUBAI (REUTERS) - Portuguese winger Ricardo Quaresma has ended his turbulent spell at Turkish side Besiktas after agreeing to join Dubai's Al Ahli on an 18-month contract, local media reported on Wednesday.

The 29-year-old former Barcelona, Inter Milan and Chelsea forward replaced Cameroon midfielder Achille Emana as one of the four foreign players at the club, the National newspaper said.

"It is a sign of our ambition," club chief executive Ahmed Khalifa was quoted as saying by the newspaper ahead of the player's official unveiling later on Wednesday.

"It's very rare to find a player of his quality at this time of year and the negotiations were therefore kept very secret. OK, Ahli is not Liverpool, Barcelona or Manchester United, but in this region, we hold that reputation. Ricardo understands this and is looking to be a success here."

Besiktas terminated Quaresma's three-year contract six months early in December, ending a troubled stay at the club in which he clashed with then manager Carlos Carvalhal during a Europa League clash last March.
