The 19-year-old will leave north London for Lisbon after signing a long-term contract with the Portuguese giantsArsenal youngster Chris Willock has signed a five-year deal with Benfica.
Willock's contract with the Gunners was set to expire on July 1 and the 19-year-old has rejected an extension to remain with the club in favour of moving to the Portuguese giants.
“Overall I would be very comfortable to play him now but of course there is a lot of competition for places because there are players like Walcott, Alexis and Welbeck in front of him at the moment.
A skilful winger who has previously played in central midfield, WIllock has regularly trained with the Arsenal first team and was named on the bench for the FA Cup win away to Hull City last season, but the likes of Reiss Nelson and Ainsley Maitland-Niles are both currently considered above him in the pecking order to the senior squad.
Willock's younger brother Joe is currently part of the Arsenal academy set-up and older brother Matty joined Manchester United in 2012.
