Sources: Arsenal agree €30m deal for Gabriel
Gabriel, 22, will travel to London for a medical on Monday before signing a contract at the Emirates.
ESPN reported on Tuesday that the Gunners were hopeful of signing the centre-back this summer after the Lille president Gerard Lopez said Gabriel was set to decide his future.
The Brazil under-20 international played a key role in helping Lille secure Champions League football for the last two consecutive seasons.
Arsenal boss Mikel Arteta has bolstered his defensive options ahead of the upcoming campaign with Gabriel’s signing and the arrival of William Saliba returning from a season-long loan at Saint-Etienne.
