Carvalho of Portugal wants to avoid becoming the next World Cup shock victim.

William Carvalho, a midfielder for Portugal, is motivated to prevent his team from suffering another World Cup shock when they play Switzerland on Tuesday in the round of 16.

The more anticipated teams are cautious about losing after unexpected victories by Japan over Germany and Spain and Saudi Arabia over Argentina, among other surprising results.

On Saturday, Australia came very close to forcing Argentina into overtime, so Carvalho is being cautious going into Portugal’s game.

“I’m sure we will be facing a Switzerland team with lots of ball possession, and we’re forewarned about that,” the Real Betis midfielder told a press conference Sunday.

“There have been really big surprises, that’s a fact, so we need to be focused from the very first minute to the last so that things go our way.”

Portugal fell to South Korea in their final group match, 2-1, but had already advanced to the knockout rounds and held onto first place.

Nobody likes to lose, we have to analyse the match and learn our lessons so that doesn’t happen in the future,” said Carvalho.

“I think Portugal need to play like we did in the first two matches, united from start to end.

“We know that we are up against a very tough opponent. The details will make all the difference. We need to be ready.”

In the Nations League in June, Carvalho scored as Portugal defeated Switzerland 4-0, but a week later they lost 1-0 to the same opponent.

“We lost and we won, so we know they will be a tough opponent, but what I can tell you is Switzerland will face a totally focused Portuguese team and we will do our utmost to win the game,” he added.
