If Ronaldo does return to the Premier League, I imagine he'd prefer to go back to Man Utd, there he knows the training staff, and his ex manager at Real Madrid, Mourhino. That way the transition for him would be smoother.

However Conte is a talented manager, and you never know Cristiano may want a fresh challenge and to explore London to join a Chelsea team flying high

At 32, for a footballer Ronaldo is getting on a bit in years, however he has the type of physique that suggests he could play to a high level in his mid to late 30s.
