DOHA, Qatar (AFP) — Neymar returned from injury to help inspire Brazil to a 4-1 victory over South Korea on Monday as the favorite cruised through to the quarterfinals of the World Cup.

The world's most expensive player had sat out his team's last two matches with a sprained ankle suffered in their opening 2-0 win over Serbia.

But he came back for this Last-16 tie as Tite's team clicked into gear and delivered an ominous message to their rivals, at least before easing off in the second half.

Vinicius Junior opened the scoring inside seven minutes before Neymar added another from the penalty spot to move to 76 goals for his country, leaving him just one away from tying Pele's all-time record tally.

Richarlison's brilliant goal made it 3-0 and Lucas Paqueta added another before half-time to leave South Korea shell-shocked.

Paik Seung-ho pulled one back but by then Brazil was thinking about Friday's quarterfinal clash with 2018 runners-up Croatia.

"The time has come to go further," Neymar told Brazilian broadcaster Globo, referring to their defeats in the semifinals in 2014 and quarterfinals four years ago.

"We are dreaming of winning the title, that's obvious, but we have to go step by step."

"This was the fourth game. There are three to go but we are prepared. Our minds are focused on winning the title."

The five-time world champions had not scored four goals in a knockout game at the tournament since 1998.

Here they played at times with the joy associated with the Brazilian national team, the players coming together to celebrate each goal by showing off their dance moves and their coach even joining in.

If they finished playing within themselves, their first-half display was superb and a fitting tribute to the great Pele.

The Brazilian legend had said he would watch the game from the Sao Paulo hospital to where he was admitted last week for cancer treatment, and supporters in Doha's Stadium 974 unfurled a banner with a get well soon message to him.

It was a chastening experience for Son Heung-min and South Koreans, who have still never won a World Cup knockout match outside their own country.

Their coach Paulo Bento later announced he would not be continuing in the role.

"I believe we can be very proud of what we have done at this World Cup, and what we have done over the last four years to get here," Bento said.

Tite made 10 changes to the Brazil team after rotating his squad for last Friday's inconsequential 1-0 loss to Cameroon, with Danilo also returning from injury at left-back.

With Alisson Becker back in goal and Thiago Silva and Marquinhos playing too, this was Brazil's first-choice defense but their forwards quickly put the tie to bed.

The opener came from their first shot on target as Raphinha burst away from Kim Jin-su on the right and his ball across goal came to the feet of Vinicius who coolly picked his spot.

They then won a penalty as Richarlison was caught by Jung Woo-young and Neymar duly beat Kim Seung-gyu — his last six goals for Brazil have now all come from the spot.

Alisson was then called into action to tip over a vicious long-range effort from Hwang Hee-chan, but Brazil scored their third in style just before the half-hour mark.

Richarlison juggled the ball on his head three times just outside the area before laying it off to Marquinhos and then continuing into the box to get on the end of Silva's pass which he slotted home for his third goal at this World Cup.
