Adam Lallana has revealed that manager Jurgen Klopp demanded more energy from his Liverpool side at half-time ahead of their stunning demolition job of Arsenal.

Three goals early in the second-half ensured the Reds won the Premier League opener 4-3 at the Emirates after Philippe Coutinho had begun the revival by cancelling out Theo Walcott’s first-half strike.

A second stunning Coutinho goal came either side of equally sensational goals from Adam Lallana and Sadio Mane, which was enough to overwhelm a late Arsenal revival inspired by goals from Alex Oxlade-Chamberlain and Calum Chambers.

Lallana, who gave Liverpool the lead when he chested down Geroginio Wijnaldum’s cross and emphatically finished past Petr Cech,  has revealed what his German boss said at the half-time interval.

“He wanted us to get up to the ball more, more pressure, more counter-pressing,” Lallana told Sky Sports’ Super Sunday programme in a post-match interview.

“He said to use how fit we are and how we can really push on in the second half.

“We came out the traps firing and got the second, third and fourth goals. We let them come back in it and it was a bit of a tense last 10 minutes. It was nice to hear the final whistle and get three points, and we can go home happy.”

The former Southampton captain joined Liverpool in 2014 joining then manager Brendan Rodgers in a £25million move.

The fleet-footed attacker has starred in 90 encounters for the Reds in all competitions, scoring 13 goals from his attacking-midfield position.

Liverpool are looking to improve from their eighth placed finish last season and the club will be delighted with their victory away at the Emirates.

Jurgen Klopp will lead his side to Turf Moor on Saturday, as they gear up for a clash against newly-promoted Burnley.
