Les Dogues have endured a disappointing campaign in Ligue 1 and found themselves down in 11th before last night's clash at the Grand Stade Lille Metropole.
"We are on a good run and the players are good right now," Ligue1.com quotes Garcia as saying.
"Everybody's working hard and we know we need to put a run of wins together if we're to climb the table.
"We were at home and playing against a side that stood fifth in the table, a side in form. That raised our performance. We were fluent and enthusiastic in our play."
Lille travel to Ajaccio next Saturday.
