Real Madrid superstar Cristiano Ronaldo believes that Chelsea, which he described to be favourites in winning the Premier League, will spoil Louis van Gaal's debut season as Manchester United boss.

The Blues are on a 9-game streak without a loss, while the Red Devils can't seem to be consistent after winning back-to-back games against West Ham United and Everton, respectively, escaping their following two games with a point each opposite West Brom and the Blues.

"You can never write off Manchester United. It is only the beginning but it will be tough for United to win the title this year I think because they are already too many points behind Chelsea in my opinion," said the Portuguese.

"Chelsea are a little bit stronger than all the other teams this year."

Nevertheless, Ronaldo believes that the unpredictability in England's top-flight, which has a relatively more level playing field as compared to other domestic leagues in Europe, might surprise everyone after everything has been said and done in the ongoing term.

"But of course in the Premier League over a season you never know what can happen," he added.

"That 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."

"Chelsea have made a great start and they can be champions. I hope Manchester United can come again at the top of the league."

"At the moment they are many points behind Chelsea and have had some disappointing results at the start of the season. But let's see what happens it is an exciting league and anything can happen."
