Juventus ace Cristiano Ronaldo has admitted he has been playing with injuries in recent weeks, heavily affecting his form.
The attacker further suggested that coach Maurizio Sarri was right to substitute him, even though he was not pleased.
Ronaldo was withdrawn for the in-form Paulo Dybala in their 1-0 win over AC Milan in the Serie A, with the Argentine scoring the winning goal.
The former Real Madrid man reacted angrily to the substitution, his second in a row, and walked down the tunnel to the changing rooms visibly angry.
Sarri later defended him, saying no player loves being substituted and he would be surprised if he acted otherwise.
"In the last three weeks I have been limited," he told A Bola.
"Everyone knows that I don't like to be substituted, but there was no problem in my gestures after the change. I tried to help Juventus by playing injured,"
"No one likes to be replaced, but I understand it because I wasn't well in those two games. I wasn't 100%,"
Ronaldo was in imperious form for Portugal for the Euro qualifiers, scoring four goals in two matches including a hat-trick against Lithuania.
His goals took him to 99 in total for the national team and has the record of most international goals in sight.
