Paris Saint-Germain head coach Luis Enrique praised his players' ambition on Monday after they blitzed Atletico Madrid 4-0 to launch their campaign for a fifth trophy of the year at the Club World Cup in the United States.
PSG claimed the French Super Cup in January and followed the success up with the Ligue 1 title, the Coupe de France and Champions League.
"It has been a very long season," Enrique told broadcaster DAZN. "What I see in training is motivation. That's the objective."
The game at the Rose Bowl in Pasadena kicked off at midday in temperatures of 31C.
"It's not easy to play in these conditions in this heat," Enrique added. "We played a very good match. Mobility is important, it's one of our characteristics but you have to know when to use that mobility."
PSG took the lead after 19 minutes when midfielder Fabian Luiz finished off a slick move on the edge of the Atletico penalty area with a shot past goalkeeper Jan Oblak.
Vitinha doubled PSG's advantage on the cusp of half-time.
After the break, Julian Alvarez thought he had halved the deficit but his strike was ruled out because of Koke's foul on Désiré Doué in the prelude to the goal.
Atletico wilt in heat
Clément Lenglet compounded Atletico's woes when he was sent off in the 77th minute for a second bookable offence and substitute Senny Mayulu effectively wrapped up the game 10 minutes later when he stabbed home from close range.
Kang-in Lee added the fourth from the penalty spot in stoppage time.
"We're happy with a difficult match," Enrique added. "It was difficult to make those efforts but that's the ambition of the players. It's great for a coach to see that. Everyone is ready."
PSG, like Atletico Madrid, qualified for the 32-team tournament on the basis of their performances in the Champions League between 2021 and 2024.

"When we had the ball, we couldn't always link our lines effectively," Atletico boss Diego Simeone told Mundo Deportivo.
"In terms of determination and commitment, I saw a team that tried but couldn't get the job done.
"PSG is a team full of young talent. When Luis [Enrique] needed support on the left flank, PSG simply splashed out 70 million euros to sign Khvicha Kvaratskhelia in January."
PSG face the Brazilian outfit Botafogo – 2-1 winners over Seattle Sounders – in their second Group B game in Pasadena on Friday a few hours after Atletico play Seattle Sounders.
The top two from the pool move into the last-16 knockout stages.
"We're working together as a team," Enrique added. "That's the right way to grow."
