He was rested for the last six Portugal games while he settled at new club Juventus, where the 34-year-old has silenced sceptics with a steady stream of goals and a hat-trick in Juve's 3-2 aggregate Champions League last-16 win over Atletico Madrid.
"After the World Cup I needed a break to settle in at Juventus," he said after the Atletico win.
"In the coming matches I hope to bring my contribution to the national side. I also miss that," Ronaldo told DAZN.
Ronaldo, the five-time world player of the year, made a huge contribution to Portugal winning Euro 2016 in France, and he was also influential at the last World Cup, scoring four times including a hat-trick against Spain in their run to the last 16.
Ronaldo claims he had a consensual relationship with a former model who lodged a complaint claiming she was raped at his hotel suite.
