Liverpool manager Jurgen Klopp hit back at television pundit and former Manchester United captain Roy Keane after the Irishman described the Premier League champions' defending in a 3-1 win over Arsenal on Monday as "sloppy."

Liverpool have won all three of their league games so far this season, beating visiting Leeds United 4-3 and winning 2-0 at Chelsea, but while praising Klopp's side Keane said they had shown the ability to win while not being perfect in defending.

"Strangely enough if you look at Liverpool, they have been sloppy against Leeds, OK done well against Chelsea, sloppy again tonight, but they have got nine points, maximum points, so they will know they need to improve," noted Keane.

"It looks like they are capable of winning football matches without being at their best and that is a sign of a good team."

But Klopp pounced on Keane's comments.
