Carlo Ancelotti says his players' collective attitude is more important than tactical strategy as Brazil step up their preparations for next year's World Cup.

The Italian stepped into Brazil's dugout in May, having left Real Madrid at the end of last season, and he has ensured the Selecao's qualification for the tournament in the United States, Canada and Mexico.

Brazil have had two wins, one draw and one loss under Ancelotti so far, with a shock 1-0 defeat to Bolivia in their final qualifier meaning they finished fifth in the CONMEBOL table.

Brazil will face South Korea in a friendly on Friday before travelling to face Japan on Tuesday.

Ancelotti has alternated between different formations in his first four matches as he continues to try and find their best system ahead of the World Cup, but he knows that is only part of the puzzle.

"I think more tactical work is needed to refine game strategy," Ancelotti said.

"All of this can be very important, but the most important part is not the strategy; it is the attitude of the players on the pitch. For that, it doesn't take much time to prepare.

"I really liked the team's defensive play in June and September. The team defended very well – compact, united, committed and intense.

"Where the team needs to improve is with the ball in possession. The team has to show the individual quality it has, and we have a lot of it.

"You can play with four, three or five in attack, but what matters is the quality shown on the pitch. What I really like is the team atmosphere. It's very positive because of the players' attitude and professionalism."

At the last World Cup in 2022, Brazil were knocked out in the quarter-finals by Croatia on penalties.

Brazil are aiming to win a record-extending sixth World Cup in July next year but have not lifted the famous trophy since 2002.

Ancelotti says everyone in the squad has their eyes on the prize, adding: "Each of us thinks about the goal, which is very clear: we have to win the World Cup, not be the best players in the world.

"I want players who think they want to be in the World Cup to win, not to be the best."
