COPENHAGEN — The international future of Portugal superstar Cristiano Ronaldo hung in the balance after the 41-year-old walked out on the squad after learning that he would not start the game against Denmark yesterday.

Ronaldo announced late on Wednesday that he had left the team, shortly after a press conference in which coach Jorge Jesus confirmed the five-time Ballon d’Or winner would be left out of his starting line-up for a second consecutive Nations League game.

In his absence, Portugal turned on the style to beat Denmark 4-2.

The former Real Madrid forward had been due to train with his teammates at the Parken Stadium on the eve of the game, but walked out following the announcement by Jesus.

“Following the national team coach’s press conference, and after having a conversation with the Portuguese Football Federation president, I decided to leave the national team’s training camp,” Ronaldo wrote on Instagram.

He had already spent the entirety of Sunday’s 2-1 Nations League win in Norway on the bench, having captained the side in the 1-0 home victory over Wales last Thursday.

Ronaldo appeared to indicate that the reasons behind Jesus’s decision ran deeper, and hinted at a departure from the national team he has graced for more than two decades.

“In due course, I will tell the truth to all the Portuguese people about my reasons for leaving the national team, to which I have always been dedicated,” Ronaldo said.

“Now is time to wish good luck to Portugal and to all my team-mates, without exception.”

Spanish sports daily Marca said that Jesus and Portuguese federation president Pedro Proenca followed Ronaldo to Copenhagen airport in an attempt to persuade him to stay with the squad, before the player boarded his private jet.
