Arsenal have reached an agreement with Brighton to sign Belgium forward Leandro Trossard.
The Gunners have been in the market to bolster their attacking options in the January window and have now agreed a fee for the 28-year-old.
It is understood that the deal struck between the two Premier League clubs is worth £21 million (€24m) plus add-ons.
Arsenal are keen to add strength in depth to their attacking options ahead of the title run-in, with summer signing Gabriel Jesus still some time off returning from a knee injury suffered at the World Cup.
They were close to agreeing a move for Ukraine international Mykhailo Mudryk, only to be gazumped by Chelsea after a delegation from the Blues travelled to Turkey to strike a deal with Shakhtar Donetsk which instead took the winger to Stamford Bridge.
While Chelsea paid a reported up-front fee in excess of £60million for Mudryk, Trossard will set them back much less than that.
Trossard, who featured in all three Belgium fixtures in Qatar, was not part of the Brighton squad that beat Liverpool 3-0 on Saturday, with teenage Ireland striker Evan Ferguson benefitting from his recent exclusion.
Seagulls boss Roberto De Zerbi openly questioned the forward's attitude as links to Tottenham began to emerge.
