Jamie Carragher says Liverpool have got to recapture a winning mentality if they are to close the gap on Manchester United and Man City in the second half of the season.

Liverpool suffered a shock 1-0 defeat to Burnley on Thursday as their poor run of recent form continued.

It means Jurgen Klopp's side now sit six points off league leaders Manchester United and four points off Man City, who have a game in hand.

Speaking on Sky Sports, Carragher argued that it could be a sign that Liverpool's title-winning and Champions League-winning side may be coming towards the end of its natural cycle - and that it is a big test of their mentality if they are to close the gap on the league leaders.

He said: "Everyone at this moment is going to have questions thrown at them and no-one ever gets it perfectly right, even when they’re at their absolute best.

"But at this moment, this Liverpool side are a shadow of what they’ve been in the last three or four years. Normally after three or four years, there’s almost a moving on.

"I mentioned about Roberto Firmino on Monday Night Football and very rarely do you see the same players playing week in and week out. You actually go back to the Champions League final that Liverpool lost to Madrid, if you look at Liverpool’s team that night, it’s still the team today, really, with one or two exceptions.

"Certainly the 10 outfield players, apart from Fabinho coming in, but it’s still the same front three, it’s still the same back four, virtually, it’s still Wijnaldum and Henderson, so there’s only been one addition, really, who you’d say is a nailed on start when everyone’s fit out of the 10 outfield players.

"That shows how much these players have done for Liverpool over the past few years with the intensity they play at and between now and the end of the season, they need to make sure they get Champions League qualification before they think of anything else and then see what the club and the manager do in the summer.

Manchester United beat Fulham 2-1 thanks to goals from Edinson Cavani and Paul Pogba.

Pogba once again turned in a high-class performance as Ole Gunnar Solskjaer's side reclaimed top spot in the Premier League. Now United turn their attention to another clash with rivals Liverpool, this time in the FA Cup fourth round.

"There will be frustration for the supporters as it looks like it’s slipping away, but there’s still half a season to go. This team has been described as mentality monsters by the manager and it’s a fitting description given what they’ve done, but they’ve got to show it and more in the second half of the season if they want to claw that deficit to the two Manchester clubs back now."
