Zinedine Zidane fielded his regular starters before the Paris Saint-Germain match and Real Madrid will travel to France boosted by a good performance by its stars and a comfortable win in the Spanish league on Saturday.
Cristiano Ronaldo scored twice and Gareth Bale once as Madrid eased past 10-man Getafe 3-1. The Los Blancos saw their star striker Ronaldo return after the shock defeat to Espanyol.
Madrid face PSG in the last 16 of the Champions League on Tuesday, leading 3-1 from the first leg.
"It was important to win before a match like we have on Tuesday," Zidane said. "We will have three days of good mood in the squad."
Ronaldo became the fastest player to reach 300 goals in La Liga, taking his tally to 301 in 286 matches. He goes to Paris having scored 10 goals in his last five matches in all competitions.
Madrid is in a fight for third place with Valencia, which is only four points behind going into its home match against Real Betis on Sunday.
Spanish leader FC Barcelona hosts second-place Atletico Madrid on Sunday to defend its five-point advantage.
Zidane rested Ronaldo and other starters this week when it lost at Espanyol 1-0.
He played with the "BBC" trio of Karim Benzema, Bale, and Ronaldo on Saturday, a sign of his possible lineup for the match against PSG. Left back Marcelo returned from injury as a second-half substitute.
Bale opened the scoring from close range in the 24th minute. Ronaldo made a pair of nice moves to clear defenders inside the area in first-half injury time for his first. His second goal was a header in the 78th from a pass by Marcelo.
Ronaldo, who had a goal disallowed for offside midway through the second half, was substituted shortly after his second goal.
Getafe's lone goal was a 65th-minute penalty kick converted by Francisco Portillo.
Getafe, 10th in the standings, played a man down from the 47th after striker Loic Remy was sent off for a reckless foul on Nacho Fernandez.
