Lee: Honestly Brazil have not been that good. They have looked questionable in defence and going forward ran out of ideas in the second half. How many of the Brazil team would you have in the England side? Two maybe three?

Four minutes of injury time to go.

The second half has been half-hearted from Brazil. They are thinking about Croatia and the next test.
They were good enough to win this in the first half. South Korea have played some okay stuff.

South Korea get away with one after goalkeeper Kim Seung-gyu gifts the ball to Brazil, but Rodrygo can't finish it off.

Paik Seung-ho had only entered the final third three times before smashing in that consolation for South Korea.
He decided to put the laces through it and it certainly paid off.

Brazil goalkeeper Alisson is off and third-choice keeper Weverton, the only member of the Brazil squad to not see any minutes so far in this World Cup, gets on for 10 minutes plus injury time.
Neymar is also heading off, with Rodrygo coming on.

Incredible strike!
Must be all of 25 yards out. It does take a slight deflection. Even the great Alisson couldn't keep that out.

Paik Seung-ho (South Korea)
A wonder strike from 30 yards!
A free-kick is played into the Brazil penalty area and it is headed clear. But then, out of nowhere, South Korea substitute Paik Seung-ho hits it from distance. It takes a slight deflection, but still flies into the top corner. Alisson finally beaten, and in some style.
It won't change the outcome of the match, but what a moment for Paik Seung-ho.

Thiago Silva has rarely been threatened in defence as Brazil have dominated the ball for large spells.
The classy centre-half has played his part in a high Brazilian back line, from which he has pulled the strings like a quarter-back.
The Chelsea defender has made 71 passes, more than any other player on the field.

Another couple of changes for Brazil as Gabriel Martinelli of Arsenal and Bremer of Juventus both come on, with Danilo and Vinicius Jr heading off.

Dogged, determined defending from Brazil.
4-0 up and they aren't letting one pass.

Brazil are four up and coasting, but Alisson has just made his third excellent save, one-handed to keep out Hwang Hee-chan's powerfully hit half volley.
The rebound falls to Tottenham's Son Heung-min but his shot is blocked by a fantastic challenge from Marquinhos.
Brazil 4-0 South Korea

Brazil have lost that snap with their passing. They know this is over and they want to ease through.
Brazil 4-0 South Korea
Dani Alves on, Eder Militao off in the first of the Brazilian substitutions. Militao would've missed the quarter-final if he'd picked up a yellow card so it makes sense.

Brazil break at pace and it's a five v five chance. Neymar plays in Raphinha, but Kim Seung-gyu makes a good save to parry it away.

Mark: Ridiculous and disrespectful that people are writing off Croatia off already. South Korea haven’t shown up, the next game won’t be so easy. If you want proof of that, check out who actually made the final last time round.

Neymar is rousing the crowd.
The showman.

Raphinha takes a free-kick from 25 yards out, but it flicks off the wall for a corner, which Neymar walks across to take. But they play it short and the cross is soon headed away.

Olly: Let's be honest, this is absolutely Seoul destroying.
