Atletico have already assured themselves of a place in next season's Champions League by finishing in the top four in La Liga, but Marseille, now in the Europa League spot in Ligue 1 with one game remaining, would guarantee their passage by winning the final.
"The fact we played a day earlier against Guingamp is an advantage".
Key to their success has been the switch from a 4-3-3 formation to a 4-2-3-1. The former Newcastle flop has been in stunning form under Garcia, netting 26 goals and providing 17 assists in all competitions. Meanwhile, the subsequent rise of their domestic and, in PSG's case, most hated rivals has led to Marseille fading into relative obscurity.
The French side, on the other hand, are looking to win the Europa League for the first time and while they had an easier road to the final, having overcoming Salzburg, they should not be dismissed, especially given the attacking flair offered by Dmitri Payet and Florian Thauvin.More news: Wide Fuselage Aircraft Market 2018 - Boeing, Airbus
They can avoid that tense scenario by finding a way through a formidable Atletico defence and clinching not just a shock triumph and a European trophy, but also an immediate place in next season's Champions League group stage.
"They have the experience but we've studied our opponents and we'll know how to take them on", he said.
"I feel a lot better - yes, I feel I can play tomorrow", he told reporters ahead of Wednesday's match in Lyon, France. "It's been shown before that anything's possible".
Marseille are aiming to become the first French team to win the Europa League and add European club football's second-biggest prize to the Champions League trophy they claimed a quarter of a century ago with a famous upset win over a hotly fancied AC Milan.More news: Celtics blow out the Cavs in game 1
"We know that Atletico stand in our way and that it will be a very hard mission, but that would make it an even greater achievement if we managed to win the trophy".
"Experience is a little thing that can help but it's not going to have too much influence. We're also strong on free kicks".
"They will have self-confidence, and we will need to impose our rhythm as the game goes on".More news: As president commissions EFCC office…: Corruption forced me out in 1985
