Goals from Sean McConville and Offrande Zanzala gave Stanley a memorable 2-1 victory over Olympique de Marseille at the AJ Bell Stadium in their second pre-season friendly.
The French giants are on a training camp at St George's Park and the Reds came up against a host of internationals.
However McConville headed home the opener and a Zanzala spot kick gave them the advantage at the break which they held onto – with both sides making a host of changes in the second half.
It was André Villas-Boas' side who created the better chances in the opening stages, with Valère Germain forcing a save out of Dimitar Evtimov while Isaac Lihadji turned in the area but his close range shot was blocked.
The Ligue 1 side, who finished fifth last season, had a great chance to score when Morgan Sanson got the ball in the area unmarked but he rifled it over the bar.
Stanley were always a threat though and a McConville free kick wasn't far from sneaking in at the far post.
Marseille came close on 24 minutes when Dimitri Payet, who broke Stanley's hearts in their EFL Cup game at West Ham, played in a free kick, Boubacar Kamara got his head to it but a Stanley trialist headed it off the line via the underside of the crossbar.
Then Stanley took control, they opened the scoring on 28 minutes when Jordan Clark played a superb deep ball from the right, keeper Yohann Pele missed it and McConville guided the ball home with his head.
Stanley doubled their advantage on 37 minutes when McConville went on a mazy run into the area and was brought down in the box, Zanzala stepped up to take the penalty, in Billy Kee's absence, and he sent Pele the wrong way.
Payet tried his luck from range but Evtimov was equal to it while Sam Finley's looping header was just over the crossbar.
Saif-Eddine Khaoui blasted over inches over just before the break as Stanley celebrated a 2-0 lead at the interval.
Stanley made one change in midfield at the break, a trialist replacing Sam Finley, while Marseille put ten players on including Florian Thauvin, who was part of the French 2018 World Cup winning squad.
Chances were limited with Niels Nkounkou hitting the side netting for Marseille while goalscorer Zanzala hobbled off following a tackle, with Okera Simmonds replacing him.
Stanley added more subs on the 73 minute mark as John Coleman gave gametime to the majority of his squad.
Marseille got one back on 77 minutes when Thauvin finished well after making space for himself in the box.
Evtimov pulled off a superb save four minutes from time to keep out a Kevin Strootman point blank header while Thauvin's last ditch free kick was just over the bar as Stanley held on for a prestigious win.
