#3 Calum Chambers
A product of Southampton's famed academy, Arsenal's Calum Chambers was highly rated during his days with the Saints.
However, things have not gone according to plan for the player at the Gunners. Chambers joined Arsenal in 2014 for £18.2 million, but has not been a regular in the first XI. Capable of operating as a centre-back, right-back and defensive midfielder, Chambers has struggled to get going at the Gunners.
The England international has enjoyed loan spells with Middlesbrough and Fulham during this period. His time with Fulham was particularly fruitful, with Chambers winning the Fulham Player of the Year for his performances. The 26-year-old has made only three appearances in all competitions this season, so a fresh start could well suit him.
#2 Bernd Leno
Bernd Leno has been one of Arsenal's better performers under Mikel Arteta. While he is prone to mistakes, the goalkeeper has generally stood tall when called upon.
This summer, though, Leno was linked with a move away from Arsenal. Leno joined Arsenal from Bayer Leverkusen for £22.5 million in 2018, and has been the club's first-choice goalkeeper since then. The arrival of Aaron Ramsdale from Sheffield United for £25.2 million this summer has altered the equation, though.
Both Ramsdale and Leno have been rotated by Arteta so far this season. It has been reported that the Spaniard prefers Ramsdale due to his ability on the ball. With the FIFA World Cup next year, Leno will be keen to be a part of the German national team. The 29-year-old has been linked with German clubs, where he could he headed to in January.
#1 Alexandre Lacazette
Alexandre Lacazette is unlikely to be an Arsenal player for much longer, with his current contract expiring next summer.
There has been little to suggest that Arsenal are going to offer him a new contract. Lacazette has done well for Arsenal since joining from Lyon in 2017 for a then club-record fee of nearly £48 million. The France international might not be a prolific goalscorer, but his work ethic and technique have been useful for Arsenal.
Letting go of Lacazette will free up wages, as Arsenal seek to refresh their forward line. The 30-year-old has been linked with the likes of Atletico Madrid and AC Milan. Arsenal, meanwhile, have been suggested as a potential destination for strikers like Luka Jovic and Dominic Calvert-Lewin.
