Following Cristiano Ronaldo's apparent breakdown in relationship with his manager at Juventus, a former Real Madrid star believes the Portuguese superstar has a major issue with Maurizio Sarri.
The 34-year-old has struggled for form in Italy as of late, although there have been questions about his fitness due to a niggling knee injury.
His manager Sarri has attempted to play down the former Real forward's poor goalscoring form by blaming it on the player not being at his physical best, despite his recent exploits with Portugal.
Last month, the Juve boss substituted the striker in two consecutive matches, with Ronaldo reacting angrily on both occasions, leading many to believe their working relationship has taken strain.
Former Italy attacker Antonio Cassano has now echoed these sentiments.
"I think Ronaldo has a big problem with Sarri," he told Tiki Taka.
"Everything started with the two consecutive substitutions, which would irritate any player.
"In my opinion, there's a problem between them, and Juventus have succeeded in playing it down."
Ronaldo has scored just seven goals and assisted a further two strikes in 16 matches for Juve so far this season.
