Mikel Arteta has been eager to strengthen his attacking options as the Gunners pursue a first Premier League title since 2004 and Belgium international Trossard, 28, fits the bill.
Brighton will receive a guaranteed figure of around £20m with the remaining £7m made up of achievable incentives – and the Gunners have handed Trossard the No.19 shirt – previously worn by Nicolas Pepe.

Trossard could be in the Arsenal squad to face Manchester United in a pivotal clash at the Emirates Stadium on Sunday, with the club revealing they had submitted all of the necessary paperwork to the Premier League.
After the signing was confirmed, Arsenal boss Arteta said: ‘It is good work from everyone at the club to complete the signing of Leandro.
‘He is a versatile player with high technical ability, intelligence and a great deal of experience in the Premier League and at international level.
‘Leandro strengthens our squad as we head into the second part of the season and we’re all looking forward to working with him. We welcome Leandro and his family to Arsenal Football Club.’
The Gunners’ Sporting Director Edu added: ‘We’re delighted to have completed the signing of Leandro Trossard. We have a clear plan and strategy for our direction, and it’s been a great team effort in bringing Leandro to the club.
Arteta and Edu both outlined their delight at completing the signing of the 28-year-old forward
‘Leandro is a player who will give us a high level of quality going forward. I know Mikel and our coaches are excited to start working with him. Welcome Leandro!’
Sportsmail understands that Trossard can expect to double his current salary to around £90,000-a-week at the Emirates Stadium.
He takes over the No.19 shirt from Gunners outcast Pepe, who has struggled since his £72m move to the Emirates from Lille in 2019 and is currently out on loan at Nice.
Pepe is still contracted as an Arsenal player but the loss of his shirt number suggests Arteta sees no future for the winger at the club.
