Mason Greenwood scored 10 goals for Getafe last season
Mason Greenwood scored twice on his debut as Marseille began the new Ligue 1 season with a resounding 5-1 victory at Brest.
The 22-year-old joined the French club from Manchester United in a deal worth up to £26.6m in July.
He opened the scoring after just three minutes, driving in from the right and firing into the bottom corner.
Luis Henrique made it 2-0 in the 26th minute before Greenwood got his second from the penalty spot five minutes later.
Mahdi Camara got one back on the stroke of half-time for Brest, who lost just twice last season, but second-half strikes by Henrique and debutant Elye Wahi sealed the big win.
Greenwood was a product of United's academy but had not played for the Premier League club since January 2022 and was on loan at Getafe last season before making the permanent move to Marseille.
Serious charges against him, including attempted rape and assault, were dropped in February 2023.
The French club were criticised by the Marseille mayor after their intention to sign Greenwood was made public.
