Koke hasn't developed into the player he looked like he was going to a few years ago, Saul would be a better option for Spain.

But Silva & Asensio are no stronger that Iniesta and neither are in his class as a footballer.

Very rare that he gets the better of Godin. This world cup has highlighted that there is a shortage of top quality defenders however Godin is an exception as he is world class as he showed again tonight.

Do you work for the BBC?

Who'd have thought it Messi plays deeper behind a proper striker and is more affective

Should have gone to a proper club in a competitive league instead of following the money in a one team league.

Is Sampaoli for real bringing Meza on ahead of Dybala & Lo Celso. There's a reason that Meza is 26 and never played outside of Argentina & after the tournament he has had is never likely to.

Not sure that Icardi would improve Argentina but the best player in Serie A last season certainly would. Dybala is the only other player in this squad close to Messi's level yet he has played 20 minutes all tournament.

Otamendi is shocking Guardiola can buy all the stars he likes but he won't win the Champions League with Otamendi leading the defence.

Unstoppable, goal of the tournament so far.

If Argentina want to play with a false 9 then they should play Dybala.

But Southgate rested players to give us an easier quarter final in order to get to the semi final. If he had played our strongest side last night we would have had a much better chance at beating a weakened Belgium team, which would have meant we would've topped the group and had an easier last 16 game against Japan instead he looked further ahead and now we have Colombia.

Falcao is a different player now. When he was at United he had only just come back from an ACL and his time at Chelsea was blighted by injury. Now he is fit & has his confidence back he is not far of the Falcao of 2010-2013 although I don't think he will ever hit those heights again as he has lost a yard of pace. The only striker in the England squad better than him is Kane and at his peak Falcao was as good as him. And I would say Uruguay have turned up 3 wins from 3 no goals conceded from their rock solid defence and Suarez and Cavani both on the score sheet. At the moment they would be my favourites to win it.

Huge risk taken by Southgate, yes if we get past Columbia then we have an easier game to get to the semi than if we had won last night. But now we have a harder get just to get to the quarter final. For me Southgate has needlessly put his job on the line against Columbia.

Brazil have basically spent the last 20 minutes passing to Neymar so he can score, the problem is Neymar is not as good as he is hyped up to be and is not in the same class as Coutinho.

The Peru game against Argentina was iffy to say the least. And is disliked it when in 74 & 78 you had no knock out stages and instead had another group stage.

For me this World Cup already ranks alongside 1970 as the best World Cup I have seen. And I think it is going to get even better when the knock out stages commence.

The South Korea goalkeeper was excellent and not for the first time in the tournament. A good shot stopper and commanding on crosses. Mowbray sign him up.

Pele's predictions, always good for a laugh. http://www.goal.com/en/news/2377/top-10/2009/06/23/1338375/top-10-wrong-pele-predictions The thing with Mascherano is that he hasn't played that position in club football for about 7 years & he doesn't have the legs to play in there now. He should be playing in his best position which is centre back & if he did he would be Argentina's best centre back.

You must be the only person outside of Iceland who would have wanted to see Iceland progress. It's been a World Cup of fantastic attacking football, the last thing it needed was Iceland going through playing anti football with 10 men behind the ball for the majority of the game. I'm personally delighted to them and their style of football where it belongs, out of the World Cup.

God bless the Pope, God bless Maradona & God bless Messi. Vamos Argentina

Great finish, but an Iceland goal would still knock Argentina out.

Argentina heading out of the World Cup and Dybala has played just 20 minutes

Iceland equalise.

Meza has been shocking in both games. How has he been brought on ahead of Aguero, Lo Celso and Dybala.
