His return to the France squad is set to cost Manchester United £8.7million.
The 23-year-old is poised to make an international comeback after Les Bleus boss Didier Deschamps admitted the forward is “back at a very, very good level".
Martial's deal from Monaco in 2015 included an add-on triggered by 25 caps for his national team.
He needs to play 45 minutes in the game for an appearance to count and is so far on 11 before losing his place in Deschamps' squad for the World Cup, says The Sun.
The France boss is now considering a recall for next month's European Championship qualifiers against Moldova and Iceland - and Martial could hit the 25-cap mark before the end of the 2020 campaign including finals.
Martial will also trigger another £8.7million payment if he is named as a nominee for the Ballon D'Or award.
