The club revealed the final three-man shortlist on Tuesday.
Saka, 18, was promoted to the first team in 2018 and has enjoyed a breakthrough season with the Gunners, becoming a key figure in Mikel Arteta’s squad.
He has scored four times and provided 12 assists across all competitions, playing in different positions.
Captain Aubameyang recorded 27 goals across all competitions, narrowly missing out on winning the Premier League’s Golden Boot.
Leno made a string of great saves throughout the campaign, until his season was ended prematurely against Brighton and Hove Albion, after landing heavily on his right leg under pressure from Neal Maupay.
Alexandre Lacazette was named winner of the 2018/2019 season.
The winner will be decided by votes from Arsenal fans.
