DOHA, Qatar, (AFP) — Brazil must do without injured star forward Neymar against Switzerland at the World Cup on Monday as Cristiano Ronaldo looks to lead Portugal into the last 16 in Qatar.

Five-time world champions Brazil can secure a spot in the knockout phase with a win over the Swiss, who held Tite’s side to a 1-1 draw in the 2018 group stage.

Brazil kicked off their campaign in Qatar with a 2-0 victory over Serbia in Group G but Neymar limped off with a sprained ankle.

“At the time it was difficult for him and after the game he was sad which I think is normal given how much he has dreamt of this,” said Brazil centre-back Marquinhos.

“Now, after the tests and the treatment, he is doing physiotherapy 24 hours a day which shows how much he wants to be back with us.

“We don’t know when, but we hope it’s as soon as possible.”

Switzerland centre-back Nico Elvedi said side would not be awed by the might of Brazil, insisting they had enough quality to push the tournament favourites.

“Every team in this world is beatable,” said the Borussia Moenchengladbach defender.

“We know the challenge, but we are not going to hide away. We know our quality and what we are able to show.”

Ronaldo became the first man to score in five World Cups after converting a disputed penalty in Portugal’s opening 3-2 victory over Ghana in Group H.

The Portuguese will qualify for the second round if they beat Uruguay at the Lusail Stadium, which will host the final on December 18.

Danilo Pereira has been ruled out of the rest of the group stage after fracturing three ribs in training, meaning 39-year-old Pepe is likely to start in defence.

It would make him the second oldest outfield player ever to appear in a World Cup match, after Cameroon great Roger Milla.
