Champions Marseille have cut Lille's advantage to a point with seven games left after the leaders drew 1-1 at home with Girondins Bordeaux last Saturday having surprisingly lost 1-0 at struggling Monaco the weekend before.
But Marseille are busy playing Montpellier on Saturday in their League Cup Final before Lille, buoyed by Tuesday's semi-final success over Nice in the main French Cup competition, visit seventh-placed FC Lorient on Sunday.
"We are aware that we are experiencing something historic," Garcia told reporters after the 2-0 win over top-flight Nice.
"After the three great seasons we have managed, we would love to leave a mark," Lille captain Rio Mavuba said.
Sunday should also pit Ligue 1's two top goalscorers against each other with Lille's Moussa Sow (21 goals) and Lorient's Kevin Gameiro (17) plotting their own personal shootout.
Like Lille, Lorient will be keeping an eye on Saturday's League Cup Final too given they currently lie just outside the Europa League places.
Third-placed Olympique Lyon, whose outside title hopes were rocked by last Sunday's 1-0 defeat at Paris Saint-Germain in fourth, are not in action this weekend given the final while PSG travel to 11th-placed Stade Brest - who are still not safe.
