An extra-time goal from Rolando against Red Bull Salzburg saw Marseille book a spot in the decider 3-2 on aggregate despite a 2-1 loss.
The clash in Salzburg was just the latest to be marred by controversy in European football this week, with Rolando's goal coming from a corner incorrectly awarded to Marseille.
Garcia would welcome the introduction of the VAR in the Europa League, saying it could eliminate mistakes.
"I can't wait for VAR," he said. "That way we won't talk about their second goal, where they had a man offside.
"We wouldn't have to discuss the penalty we weren't given for a handball in the box, or the corner we were given which led to the goal, which should have been a goal kick.
"VAR will put an end to this."
An Amadou Haidara goal had earlier given the hosts hope before Bouna Sarr's own goal drew them level in the tie.
Garcia was delighted for his team and he is desperate to cause an upset in the final against Atletico Madrid in Lyon on 17 May (AEST).
"I'm very satisfied. Getting to the final isn't an end in itself," he said. "We're obviously outsiders against Atletico, in France, in Lyon, at home for this final.
"Even if they have a better chance of winning we'll do our best to win the trophy. It's not enough to get to the final, we don't want to end such a nice run."
