Roberto Martinez hailed the experience of Cristiano Ronaldo as the 38-year-old scored twice in Portugal's 6-0 thrashing of Luxembourg.

Ronaldo followed up his brace against Liechtenstein on Thursday with another on Sunday at the Stade de Luxembourg as Portugal made it two wins from two to start their Euro 2024 qualifying campaign.

Joao Felix, Bernardo Silva, Otavio and Rafael Leao added the other goals, and Martinez was quick to praise Ronaldo for his contributions in the Spaniard's first games as head coach.

"Cristiano has incredible international experience, probably unique as he is the only player [in the world] with 198 caps," he said at a post-match press conference. "His experience is very important in the dressing room."

Former Belgium boss Martinez also claimed he was happier with another clean sheet than with his team's attacking display, and reserved praise for 19-year-old centre-back Antonio Silva, who replaced Goncalo Inacio from the Liechtenstein win.

"I value the zero goals against more than the six goals, the penalty and the great attacking game we played here in Luxembourg," he said. "This game was not easy. What was important in both games was work and consistency.

"It wasn't just changing some of the options. There are many options, it was more a change due to the physical demands. It was important to see Goncalo Inacio play well in the first game [v Liechtenstein], but for a young man, three days after a game, it was also important for him to rest.

"It was important to see Antonio Silva entering a very important position, getting on the ball and going up against Luxembourg's attack.

"It was good to see Antonio Silva together with the experience of Ruben Dias and Danilo Pereira. And Rui Patricio was also very good, so the team was very strong defensively in this game."

Portugal top Group J ahead of Slovakia by two points, with the next round of fixtures coming in June when the Selecao host Bosnia-Herzegovina.
