England star Wayne Rooney, currently on tour in the U.S. with Manchester United, believes Liverpool will be genuine Premier League title challengers this season.

Liverpool has not won the league since 1990, but the return of Kenny Dalglish as manager and a number of new summer arrivals has led to new optimism around Anfield.

"Liverpool will challenge this time," Rooney told reporters. "They've made some really good signings under Kenny Dalglish, British players, and I'm sure they will try harder than they've ever done, fighting to be up there.

"They will think they have a chance of winning the title. The main threat is going to be from Chelsea, Liverpool, Arsenal and Manchester City. One of them, plus us, will be fighting for the title."
