Chelsea striker Didier Drogba has declared this season's Premiership the toughest ever.
"The fact that the Chelsea squad has not changed much is a good thing. It will be our biggest asset this season," he told L'Equipe. "The Premier League is harder and harder every year, and the new season will be more difficult without a doubt.
"Now there are five or six teams capable of fighting for the title. Manchester City certainly have the means. I think they will need time before they are capable of beating the top four teams, but they will be up there.
"We cannot forget about Aston Villa and Tottenham either. We are not talking about a Big Four anymore, but about a Big Five or Big Six.
Drogba added: "For the last three seasons Manchester United have won the title, and they have deserved to.
"But now that is enough! We will be doing our best to change that. Of course they are the team to beat, but we showed in the Community Shield that we can do that.
"Personally, I feel fine at Chelsea and I want to win titles here. I want to win the Premier League title again, but my main priority is the Champions League. I am convinced we can do that this season."
