Arsenal forward Joel Campbell has joined Sporting Lisbon on a season long loan, it was announced on Sunday.

The Portuguese giants confirmed the signing via their official Twitter account account after it emerged on Saturday that Arsene Wenger had sanctioned the temporary exit of the 24-year-old.

The official Arsenal website confirmed the transfer as they explained that it is subject to international clearance and formal ratification.

Campbell, 24, was not included in the Arsenal squad for their opening two Premier League matches, a 4-3 defeat to Liverpool and Saturday’s goal-less draw against Leicester.

He has now sealed his fifth loan move away from the Gunners since joining Arsene Wenger’s side in 2011.

Campbell has had previous spells at Lorient, Real Betis, Olympiakos and Villarreal during what has been a nomadic career.

The right-sided forward had appeared to have established himself as a squad regular last season when he made 30 appearances in all competitions, scoring four goals and supplying six assists.

But Wenger has given Campbell the green light to depart even though Arsenal have not signed a new striker this summer and the manager has suggested that he will continue to play winger Alexis Sanchez through the middle instead.

Sanchez led the line in Arsenal’s opening two games, although main striker Olivier Giroud was a second-half substitute against Leicester.

Campbell will be hoping that the Sporting side can improve on their second placed finish last season and gain further Champions League experience.

Campbell has recently fallen down the pecking order at Arsenal, with the likes of Sanchez, Theo Walcott, Alex-Oxlade Chamberlain and Alex Iwobi ahead of him for the wide attacking roles.

Despite his relatively tender age, Campbell has 11 international goals in 63 appearances for his country.

The forward is under contract at The Emirates until the summer of 2018, but there is a strong possibility that he has played his last game for the north Londoners.

In other Arsenal transfer news, Arsene Wenger is ready to sanction a deal for this forward.
