An interesting subplot tonight - Lionel Messi could become the highest-scoring South American footballer if he bags a couple of goals.

One goal and he will move level with Pele on 77, two and he will surpass the Brazil legend.

An added bit of intrigue - especially given it will be against Brazil he takes the record, should he grab a couple of goals.

There's always a bit of spice when Brazil play Argentina but even more so in the build up to this one.

Just hours before kick-off, Brazil's health regulator Anvisa sought the immediate isolation of four Argentina players who had spent time in the UK over the previous 14 days.

Although it did not name the four, the players with English Premier League clubs are Emiliano Buendia and Emiliano Martinez of Aston Villa and Giovani lo Celso and Cristian Romero of Tottenham Hotspur.

However, it appears that the issue has been sorted, with Conmebol weighing in as three of those players are starting.

Brazil: Weverton; Danilo, Militia, Verisimo, Alex Sandro; Ribeiro, Casemiro, Gerson, Paqueta; Neymar, Gabigol

Argentina: Emiliano Martínez; Montiel, Romero, Otamendi, Acuña; Di María, De Paul, Paredes, Lo Celso, Messi, Lautaro Martínez

Four minutes in, Robert Lewandowski has his 71st international goal. You feel he might end the night on more than that.

Spain boss Luis Enrique says he is still "optimistic" despite guiding the country to their first World Cup qualifying defeat in 28 years.

Sweden, who beat Enrique's side 2-1, are two points clear of Spain at the top, with a game in hand, leaving a real prospect of La Roja needing the World Cup play-offs.

"I've watched the game back, we've gone into depth with the analysis and I'm more optimistic," Enrique said.

"We don't have things in our own hands in order to finish top of the group come November, but we have qualification for the next World Cup in our own hands even if Sweden top the group.

"If we win the two play-off games then we would qualify. You need to overcome difficulties, and that's what we're working on."

We will also be bringing you regular updates from Sao Paulo as Brazil face Argentina in World Cup qualifying.

Both sides look well placed to qualify for Qatar, sitting in the top two. Brazil have won all seven games, while Argentina are unbeaten in 21 games in all competitions.

That includes the Copa America final where they beat Brazil.

Of Europe's quarantine rules, which have denied both teams the ability to call up some players, Argentina boss Lionel Scaloni said: "It can’t go on like this.

"These games are being played because it was very tight and the decision was last minute but they need to take a decision for the next time. You can’t compete like this."
