Ben White is expected to have his Arsenal medical on Wednesday after a deal of £50m is strike between the North London club and Brighton last week.
The England international defender joined the Seagulls in 2014 from Southampton and has gone on to make 41 appearances for the club in all competitions.
He enjoyed a series of loan spells before breaking into Brighton’s first team last term. White helped Marcelo Bielsa’s Leeds United gain promotion to the Premier League when he spent the 2019/20 campaign at Elland Road.
White was selected by Gareth Southgate for England’s Euro 2020 campaign and played in the two warm-up games against Austria and Romania prior to the start of the tournament.
He also contributed to Brighton having the joint-best defence in the bottom half of the Premier League last season with 46 goals conceded.
Ben White would become Mikel Arteta’s third summer signing following the arrivals of left-back Nuno Tavares from Benfica and central midfielder, Albert Sombi Lokonga, from Anderlecht.
