Brazil and Argentina are both rebuilding after their disappointing World Cup campaigns, which has afforded young players a chance to impress.

They’ll be going head to head in international football’s biggest derby on Tuesday.

Here are four players you need to keep an eye on.

Arthur

After being named as a standby for the 2018 World Cup, Arthur now finds himself at the forefront of Tite’s plans to renew and re-energise Brazil following their disappointing quarter-final exit in Russia.

His move from Grêmio to Barcelona was like Ross and Rachel from FRIENDS. On one minute, off the next, but you’ll be hard pressed to find anybody at Camp Nou unhappy with this deal.

Arthur attempted 142 passes which, according to Opta, is the highest amount by an away player in LaLiga since 2012. And who holds that record of 148 attempted passes from 2012? Xavi Hernandez.

Having been initially eased in to the side by Ernesto Valverde, the 22-year-old has started each of Barça’s last three games and boasts the highest pass accuracy (93%) of any Barcelona player.

Likened stylistically to Xavi, his feathered first touch, surprisingly stocky frame and ability to welcome the ball in central areas are priceless for the modern game and it won’t be long before he shines for O Selecāo.

Lautaro Martínez

Because Argentina clearly needed more attacking talent progressing through, Lautaro Martínez is the latest name exciting those back at home with his impressive performances.

Much like Arthur, Lautaro rose to prominence in the Copa Libertadores – where he shone for Racing – before earning a €22m move to Inter this summer.

At 21 years-old, Lautaro Martínez has directly contributed to 31 goals in 60 senior games.

Manager Lionel Scaloni has always emphasised his desire to reward youth and after his first goal against Saudi Arabia on Thursday, it looks like that faith has been rewarded.

Comfortable on the left side, right side or through the middle, the 21-year-old is everything you could ask for in a modern forward and learning from Mauro Icardi every week. It’s frightening.

Richarlison

Eyebrows were raised when Everton paid €40m for his services in July, but Richarlison has proven himself a unique talent and deserved his call-up to the national side.

South American forwards tend to possess a specific grit about them, an attitude prioritising winning over everything and that’s clear to see when you watch the 21-year-old play.

Only two players have won 100+ fouls in the Premier League since the start of last season:

🇧🇪 Eden Hazard (100)

He doesn’t have the skill of Neymar or the eye for pass of Coutinho but he will press, harry and drive at the opposition full-back relentlessly, improving his finishing at every opportunity.

There are moments when he can frustrate or let himself down with petulant behaviour, but in difficult games away from home this is a character you want at your disposal and Tite has realised this.

Santiago Ascacibar

Small midfielders are all the rage at the moment and Santiago Ascacibar is no different. Standing at a mere 5’6″ tall, the 21-year-old can be found nipping and snapping at heels, winning the ball back and distributing with minimal fuss.

Making the move from South America to Europe is never an easy one, but Ascacibar has taken to life in Germany like a duck to water and has been an everpresent for Stuttgart since joining in 2017.

Santiago Ascacíbar (21) has signed a one-year contract extension at VfB Stuttgart.

His new deal runs through to 2023 and, crucially, doesn't include a release clause. There will be no Benjamin Pavard scenario.

Similar in profile to N’Golo Kanté or Lucas Torreira, he is an interception and tackle machine, using his mobility and reading of the game to great effect. Scaloni has done well to add some extra bite to his already technically gifted midfield.

As Marty Rubin once said, “lice don’t seem so small when they get in your hair”.
