Last season's Champions League quarter-finalists have won their last two away league games, but have not picked up all three points on their home patch since the start of February.
"We really need to win in front of our fans tomorrow at La Rosaleda, following two important away wins," he told reporters at a press conference.
"There are a lot of vital points to be earned from home matches, and our fans will help us get them.
"We're achieving positive results now and I have faith that these players will perform well and help us win the game, although it won't be easy."
Malaga, who host Espanyol this evening, currently sit 13th in the table.
