Liverpool legend John Aldridge says manager Jurgen Klopp needs to tighten up his defence to be sure of winning the title.

Aldridge says that Liverpool's title challenge could come up short if Klopp's side concede goals as cheaply as they did in the 4-3 win over Crystal Palace at Anfield.

"Jurgen Klopp will not have been happy with one key aspect of his side's performance at Anfield yesterday and it could have been costly in a Premier League title race where slip-ups are likely to be fatal," Aldridge wrote in the Sunday World.

"There were a few worrying signs in a game loaded with a few too many incidents for my liking.

"One of the great improvements in this Liverpool side has been their ability to manage a game and keep things tight atthe back on days when they fail to get an early goal. Well, they abandoned that mentality to an extent yesterday, as a side that had conceded just three goals at home in the Premier League all season let in three more in one game.

"The second Palace equaliser from a corner was especially worrying. Liverpool have not conceded goals like that since Virgil van Dijk arrived atthe club and that was a snapshot oftheir problems of yesteryear."
