The 22-year-old’s Arsenal career has not kicked on like he would have hoped.
The winger spent last season out on loan at Dutch side Feyenoord.
Nelson played less than 1,000 minutes in the league last season, scoring twice and providing four assists.

He was a mainstay in Feyenoord’s Europa Conference League team, helping his side reach the final before losing to Roma.
It was Nelson’s second loan move of his career, after spending a year in the Bundesliga with Hoffenheim.
Nelson has struggled with injuries and inconsistency throughout his time at Arsenal, which has hampered his progress.
Arsenal considered move for Nelson
Nelson returned to Arsenal this summer at a crossroads in his career.
Arsenal were trying to sign a new winger this summer, with Pedro Neto and Yeremi Pino both linked with moves.
The Gunners did bring in young winger Marquinhos, and he really impressed on his debut against FC Zurich.
The ‘electrifying’ 22-year-old was on the bench for Arsenal’s opening match against Crystal Palace.
Nelson has previously received assurances that he’ll feature for the first-team this season.

However, a thigh issue has ruled him out of all-but-one of Arsenal fixtures this season.
Arteta’s last update on his fitness suggested he was nearing a return, and he has been pictured in training.
Nelson may have to consider a move away from Arsenal in January if Marquinhos does make an impact on the first-team.
The young Brazilian could be loaned out, but only if a new signing is made and this wouldn’t benefit Nelson.
Arsenal’s plans to recruit in that position mean the writing might be on the wall for the 22-year-old.
