Juventus coach Maurizio Sarri admits he's happy working with Cristiano Ronaldo.

Sarri was speaking ahead of their Champions League clash with Lokomotiv Moscow.

He state, "Coaching Ronaldo, for me, is a source of satisfaction and pride. He has an extraordinary mentality and knows how to impose objectives on himself and the team.

“When he scored his 700th goal, he was thinking about his 800th. I think that's important for all of us who are close to him because it's contagious.

“He makes me understand that the difference lies is in the mentality: he has something more."

Sarri says no chances will be taken over Aaron Ramsey who has been missing since the international break.

“He has no problem with his muscle, tests came up negative. Under stress in training, however, he always has this feeling of fatigue in his thigh and that can be a sign of risk, so he's working to strengthen his muscle so as not to feel these sensations.

“Danilo's been training for a few days. I have some doubts about the fact that he can play for 90 minutes, but he's fine."
