Marseille, which lost finals at this level in 1999 and 2004, began with urgency, but Germain shot over after being played clear through on goal by Dimitri Payet's slick pass. Adil Rami shot wide moments later as Marseille's positive start upset Atletico's rhythm.
Afterwards, Griezmann was asked about the continued speculation linking him with a move to Barcelona but opted against providing any details on what club he will be playing for next season.
Atletico were too streetwise and also just too good for a spirited Marseille side - with two Antoine Griezmann's goals superbly finished after naive mistakes from their opponents, and Rojiblanco captain Gabi wrapping up the scoring late on. I have no doubt that there are certain things that could make it more likely that he stays. "I've never given him anything for free but he represents everything we're about", the Uruguayan is quoted as saying by Sky Sports. I have the luck to play on great teams and in the best generation of Spanish footballers but I had a concrete dream since I was young. He's given a lot to us over the years. "If he stays we'll keep growing because we are destined to keep growing". Now we are in the UEFA Super Cup, so he could play four finals with us.
Atletico captain Gabi had memorably called the Europa League a "s-- competition" when his side surprisingly dropped into it from the Champions League in December.
"Your feeling for a club gets stronger every game, every year".
Griezmann's decisive contribution helped erase bitter memories of 2016, when he missed a second-half penalty in Atletico's Champions League final loss to Real Madrid.
"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".
Victory for Atletico, who have already qualified for the Champions League, means the automatic group-stage berth will go to third place in France, a spot in which Marseille could still finish.
