Liverpool legend John Aldridge feels the team has lost some of their hunger this season.
He wrote for the Sunday World: "There are several reasons why Liverpool are rocking on the ropes right now and next Sunday's showdown against Manchester United will be the perfect chance for them to come out swinging.
"The 1-0 defeat at Southampton last Monday was the latest below-par performance from a team of champions who have achieved it all over the last couple of years.
"And therein lies the first of their problems right now.
"When you achieve everything you dream about in your profession, starting again and striving to repeat that success is never easy.
"We have seen so many sporting greats struggling to maintain their levels of excellence once they reach the top and maybe that is a factor for Liverpool right now.
"This team won the Champions League, the FIFA World Club Cup and the Premier League in a wonderful year and it would be understandable for some of the players to sit back and think they have achieved everything they need.
"I don't think Liverpool manager Jurgen Klopp and this great team he has assembled are satisfied with what they have accomplished.
"Yet subconsciously, some of the drive that was there to win all those trophies for the first time may now be lacking.
"The challenge for the group collectively is to spend the days ahead of the Manchester United game at Anfield next Sunday reminding themselves of what it feels like to win trophies."
