Cristiano Ronaldo's 2019/20 season is really yet to get going.

The Portuguese - who turns 35 in February - has seen his domestic campaign with Juventus interrupted by niggling injuries, resulting in him scoring just five goals from 10 Serie A games.

For a player of his calibre, that return simply isn't good enough.

Maurizio Sarri made the bold decision to sub Ronaldo off against Lokomotiv Moscow in the Champions League and the Italian boss did the same last night at home to AC Milan.

On the 55-minute mark, Ronaldo was hauled off for Paulo Dybala - who went on to score the only goal in Juve's 1-0 win - with the former Real Madrid man evidently not happy.

Sarri stated after the game that Ronaldo was struggling for fitness, but it seems clear that things just aren't clicking for the Portuguese right now.

As such, former Juve manager Fabio Capello took a bit of a swipe at Ronaldo after the game, stating that he 'hasn't dribbled past anyone in three years'.

"I didn't like this, it wasn't nice," Capello told Sky Sport Italia. "He must be a champion even when he comes off the pitch.

"The truth is that Cristiano Ronaldo hasn't dribbled [past] an opponent for three years. I did the La Liga commentary when he usually took the double step and left you there.

"Inside him is a super-champion, the best of all, but now there is Dybala and Douglas Costa, who made two sensational goals. Dybala in excellent condition can make the difference, as can Douglas Costa.

"They win games without Ronaldo. Juve seemed dependent on him, instead the great squad and the quality of the players helps them win anyway.

"Bravo Sarri, who had the courage to take him off, it takes personality, especially thinking that all the players in the squad can play and make a difference.

"Cristiano did it for a while, but now it's not him and he must recover - especially on a physical level. He does not have the speed and dynamism he has shown at other times."

That analogy seems a tad harsh, but it is rare that you see Ronaldo charge down the wing and take on opposing full-backs at will like he used to in his pomp.

Nevertheless, he is still a goal scoring machine and once he sorts out his fitness issues, we will probably see him thrive in Sarri's system.
