The 24year old who was introduced in the 88th minute to replace Ander Correa has been a key member of the Spanish side this season.
Marseille central midfielder Anguissa lost the ball to Gabi in a risky position and the midfielder put Antoine Griezmann through on goal.
He is the current SWAG footballer of the year.
However, Premier League Manchester United are also being heavily linked with the forward.
"Even diminished, he set up the (Valere) Germain chance".
While a late headed strike by Marseille's Kostas Mitroglou - a 74th minute substitute - could have swung the momentum, it was not to be, and the ball rebounded harmlessly off the upright.
They managed to win six of their eight matches in the tournament, with scoring 17 goals and conceding only four.
Olympique Marseille manager, Rudi Garcia, admits that Dimitri Payet was sorely missed in their Europa League final defeat to Atletico Madrid on Wednesday. However, the one that matters was that Atletico had a certain Antoine Griezmann in their squad.
"Simeone made me grow personally and professionally; I'm delighted with him and I owe him a lot, I know, so I'm very fond of him". "I think this is a reward for our persistence, a reward for our hard work, our reward for our insistence". Only compatriots Sevilla have won it more times, having won the trophy on three occasions.
But it only took one Marseille mistake for the Spanish side to snatch an undeserved lead.
The case will be heard by UEFA's Control, Ethics and Disciplinary Body on May 31.
And with Real Madrid favourites to beat Liverpool in the Champions League final next week, it could well be seven of the last ten.
