Portuguese midfielder Maniche will leave Cologne after just one season, the Bundesliga club's director of sport Michael Meier said.

"Maniche wanted to go back to Portugal with his family and we accepted his demand," said Meier.

The 32-year-old has been released from his contract, which was due to run until 2011, and is expected to join Sporting Lisbon.

He played 30 games in the Bundesliga last season and scored two goals.

Despite having made 52 appearances for Portugal, Maniche has not been included in the squad for next month's FIFA World Cup in South Africa.
