Manchester United have announced winger Nani has officially left Old Trafford after eight years in order to join Turkish side Fenerbahce.

The Portugal international was given a rousing reception by supporters upon arriving in Istanbul to complete a medical over the weekend and the BBC reports he has agreed terms on a three-year contract at Sukru Saracoglu Stadium for a fee believed to be in the region of £4.25m ($6.6m).

"Everybody at United would like to wish Nani every future success in his career," United said during a statement announcing their second departure of the summer following Angelo Henriquez's permanent move to Dinamo Zagreb.

Nani won four Premier League titles and the Champions League after joining United from Sporting Lisbon in 2008, yet despite that success often frustrated due to a lack of consistent performances.

He appeared just 11 times for David Moyes and Ryan Giggs during a difficult 2013-14 season during which the Red Devils failed to secure qualification for the Champions League and subsequently returned to his former club on loan in August 2014 as part of the deal that saw Marcos Rojo move to the Premier League.

Clearly not part of United manager Louis van Gaal's first-team plans for the future, despite notching seven goals during his temporary second stint at Estadio Jose Alvalade, Nani spoke of joining Fenerbahce as a chance to prove himself once more after a difficult few seasons.

"I'm very happy for being here. I think that there is a big chance to prove myself again. I'll try to do my best to make Fenerbahce fans happy. I hope everything goes well," he told their official website just hours before the deal was confirmed.

Nani is also keen to join up with two international colleagues in former Chelsea midfielder Raul Meireles and experienced centre-back Bruno Alves.

He said: "I know Fenerbahce very well. The club's aims have always been high and playing with Meireles and Bruno Alves will be exciting. With their help, I'll feel like I'm with my family. I want to be successful with my new team-mates."

Fenerbahce busy in the transfer window

Nineteen-time Super Lig champions Fenerbahce finished second last season, three points behind fierce rivals Galatasaray and five ahead of Besiktas. Manager Vitor Pereira, appointed in June following his exit from Olympiacos, has already strengthened his squad with the arrivals of Simon Kjaer and Brazilian striker Fernandao.

Full-back Sener Ozbayrakli has also joined from Bursaspor, while FC Porto duo Fabiano and Abdoulaye were both signed on loan deals.

Whether or not Robin van Persie joins that list of new recruits this summer remains to be seen.

The Guardian and several other publications have reported the player has already agreed personal terms with Fenerbahce, although agent Kees Vos has since confirmed to Voetbal international that his client will report for pre-season training having not yet found a new club.
