Cristiano Ronaldo admitted on Sunday that he is not at "100 percent" after reacting angrily to twice being substituted by Juventus coach Maurizio Sarri earlier this month.
The 34-year-old scored his 99th international goal on Sunday as reigning champions Portugal qualified for Euro 2020 with a hardfought 2-0 win in Luxembourg.
"I wasn't 100 percent and I'm still not," he said. "In the last three weeks, I have played at a slightly reduced capacity.
"But when it comes to sacrificing myself for my club and my national team, I do it with pride."
"I don't like to be replaced, no one does," added Ronaldo. "I tried to help Juve even when injured."
