Despite their huge victory, Arsenal failed to qualify for the UEFA Champions League, with rivals Tottenham beating them to the fourth position.
Partey, who is currently injured and played no part in Sunday’s game, hosted Gabby and his son to a dinner party in London.
Also at the dinner were the midfielder’s father, Jacob Partey, his publicist Sammy Ziga and Gabby’s son, Jasper.
“My son, Jasper, and I had the privilege of joining @Thomaspartey22 , his dad, Jacob Teye Partey, and others for dinner last night to celebrate the 5-1 victory and the end of, evidently, a progressive season under Arteta,” the NPP stalwart later posted on Twitter.
Meanwhile, Partey hasn’t featured for Arsenal in almost two months after sustaining a thigh injury against Crystal Palace in March.
However, he managed 26 appearances in all competitions for the Gunners, scoring two goals and providing one assist in the just-ended campaign.
