#3 Martin Odegaard - €40 million
Arsenal's Martin Odegaard is one of the most exciting and skilful young players in the game at the moment.
He made his debut for Real Madrid almost six years ago, but failed to break into their first team. Earlier this year, Odegaard impressed during a six-month loan stint at Arsenal. That prompted the Gunners to acquire the Norwegian permanently this summer.
Still only 22, Odegaard has impressed with his composure and ability on the ball, especially from set pieces. He has made six goal contributions (three goals and as many assists) in 26 games for Arsenal across competitions.
Arsenal will look to Odegaard for inspiration and creativity in midfield over the rest of the season as they seek to improve on their dismal eighth-place finish last time around.
#2 Thomas Partey - €40 million
Thomas Partey transformed into one of the finest defensive midfielders in the world during his time under Diego Simeone at Atletico Madrid. However, the Ghana international has had a stop-start career at Arsenal since arriving for €50 million last year.
Partey has been plagued by injuries, which have limited his time on the pitch. He has managed to play just 38 games in all competitions for Arsenal in almost two years, providing three assists.
The 28-year-old will need to up his game and live up to his lofty price tag if Arsenal hope to finish in the top six after a dismal start to their campaign.
#1 Bukayo Saka - €65 million
Bukayo Saka is one of the most exciting young midfielders in the game at the moment.
The 20-year-old has already racked up almost a century of appearances for Arsenal across competitions, scoring 13 goals and assisting 22. Saka had a breakthrough campaign last season, bagging seven goals and nine assists in all competitions.
His displays earned him a spot in Gareth Southgate's squad for Euro 2020, where he was instrumental in England reaching the final.
Saka will look to continue his development this season and evolve into a world-class player.
