Arsenal legend Thierry Henry feels he's spied a weakness in Liverpool boss Jurgen Klopp's tactics.

Henry has hailed Klopp's impact at Anfield, although he reckons the Reds need to learn when to take their foot off the gas.

"What is there not to like about Jurgen Klopp?" Henry said, speaking to The Sun.

"He is a perfect fit for Liverpool, who visit Old Trafford today in what could be a cracker.

"My only beef with Liverpool is their management of games. It is their Achilles heel.

"Their work ethic is undeniable and they high press superbly. That pressure is hard to play against — but you do not have to go 200 per cent flat out. You can manage a game.

"They were 4-1 up at Arsenal this season but rather than see it out they were running all over the place. They ended up squeaking over the line 4-3.

"That should not happen. They were in total control — and then suddenly! Bang! They're struggling.

"That cannot happen if you want to win the league.

"Yes, they bounced back from that upset by winning four of their next five but those dropped points could cost them."
