Ex-Arsenal, Chelsea and Barcelona midfielder Petit told pokerfirma.com: "When you have Cristiano Ronaldo in your team, you don't know as a manager if you have to play him in the first 11 or as a substitute, because let’s be honest, at Euro 2024 his performances were not that good for Portugal.
"But I think this guy has no limit. He treats his body very professionally, and he's 40. People may think it's probably over for him now, his international career, but this guy has so much motivation and anger, which I think could have a positive influence if he's in the team.
"When you have Cristiano Ronaldo, what do you do? Are you putting him in the first 11 every single game, or are you using him as a substitute for 30 minutes, 45 minutes? This is my question.
"Cristiano Ronaldo is such a huge name that it’s complicated for any manager to put him on the bench. The Cristiano Ronaldo situation is a really difficult one for Roberto Martinez because he’s such a superstar. It’s very complicated for him – no manager wants to be the guy that tells Ronaldo you’re on the bench or you’re not playing anymore. Because of his profile, because of his status, he’s a very difficult player to manage."
