Arsenal are reportedly hopeful that captain Pierre-Emerick Aubameyang will be the first of three first-team players to sign new contracts before the start of the season.
Aubameyang has reportedly agreed terms on a £250,000-a-week deal to end speculation over his future at the Emirates Stadium, with his previous contract due to expire next summer.
Official confirmation is expected in the coming days, and The Mirror reports that Arsenal are working on tying down two other players who have been linked with a move away.
Manager Mikel Arteta is reportedly keen to keep Ainsley Maitland-Niles at the club amid speculation linking him with a move to Wolverhampton Wanderers or Newcastle United.
Emiliano Martinez could also be in line for a contract extension, having been chosen ahead of Bernd Leno for the Community Shield victory over Liverpool.
Martinez is only willing to stay at the Emirates Stadium if he is first choice after impressing while filling in when Leno was injured towards the end of last season.
