• Portugal is at the top of Group H in World Cup 2022
  • Ronaldo scored in Portugal's campaign opener against Ghana
  • The team has already qualified for last-16

Cristiano Ronaldo is doubtful for Portugal's final Group H game in the ongoing FIFA World Cup in Qatar.

After Ronaldo missed Portugal's training on Wednesday, head coach Fernando Santos confirmed that the attacker's availability for their upcoming clash with South Korea was not certain. The exact nature of his injury has not been revealed yet, but he's reportedly dealing with knee pain.

"I think it is 50-50 if he plays or not, we'll see. It will depend on if and how he practices today, if we see he is in good condition. There is a plan for if he is not available," Santos said at a press conference.

Portugal, who have already qualified for the knockout stage, will lock horns with South Korea in their final group game Friday.

Ronaldo recently parted ways with Manchester United on mutual consent. He will be allowed to join any club on a free transfer when the winter window opens in January.

The 37-year-old forward started the World Cup campaign on a high, scoring in his side's opening game against Ghana. Portugal clinched the game 3-2.

Meanwhile, Santos confirmed that Paris Saint-Germain (PSG) defender Nuno Mendes will miss the rest of the World Cup after the left-back picked up a thigh injury in the match against Uruguay.

"Unfortunately he is out but by his will, he will stay with us. It was his desire, his club agreed, and he will start his recovery here. His enormous desire to stay with us reflects the state of mind of the whole squad," added Santos.

With Mendes, Otavio and Danilo injured, the Portuguese boss said he would look to rotate a part of his squad, trying to keep some players fresh for their game in the last 16.

"I have complete confidence in all my players, I'm already missing three players, let's see about others. Playing every four days is tough, players get tired and are experiencing fatigue. Fatigue leads to stress and stress leads to injuries," said Santos. "Winning and finishing top in our group is crucial because we will have an extra day to recover the players in the best way possible."
