Real Madrid star Cristiano Ronaldo says Chelsea will win the Premier League title this season.
Ronaldo played for Blues boss Jose Mourinho at Real.
Ronaldo said: "Chelsea are stronger than all the other teams this year, in my opinion. Of course, in the Premier League over a season, you never know what can happen.
"The period near Christmas is really tough, and you can easily drop points because there are a lot of games in a really short space of time.
"But Chelsea have made a great start and they can be champions. You can never write off Manchester United, but it will be tough for them to win the title this season... they are already too many points behind Chelsea."
