Arsenal paid €1million to Flamengo after Pablo Mari played in their 2-0 defeat to Brentford in the Premier League on Friday, Globo Esporte reports.
Sergi Canos and Christian Norgaard scored in either half to fire the newly-promoted side to victory in the season opening fixture.
Mari’s lack of pace was constantly exposed as the Brentford attackers appeared to target the 27-year-old as an area of real weakness.
As part of the package that saw the defender join the Gunners in June 2020, the Brazilian club have a series of appearance-related add-ons.
Mari was making his 20th appearance for Arsenal, triggering a clause that left the Premier League side with a bill of €1m (£850,000).
The payments won’t stop there however, as Flamengo are in line for another million for every 10 appearances he registers, up to a total of €8m.
Those clauses, along with an additional payment this summer in the region of €5m could see the total outlay reach €16m before his contract expires.
