Jurgen Klopp told his Liverpool players to stretch Arsenal by getting runners down the outside of their full-backs.
That’s according to Trent Alexander-Arnold, who spilled the beans about the tactical trick following the Reds 3-1 win over the Gunners on Saturday.
Gunners boss Unai Emery seemed to surprise Klopp by playing a diamond formation in midfield.
Arsenal settled into the game confidently and were causing the home side some problems early on.
But the visitors failed to capitalise on their chances and then allowed Joel Matip to score with a header just before the interval.
And Alexander-Arnold revealed that Klopp used video footage in the dressing room to illustrate the tactical changes he wanted his players to put into practice after the break.
“The gaffer showed us a bit of [footage] at half-time and we could stretch them, with Mo, Bobby [Firmino] and Sadio [Mane], and get it into feet,” said the right-back.
“They probably set up knowing that we were going to cross it, they were ready. [Against] other teams we try to create the yard and cross it from in front.
“The gaffer said to us at half-time, if we get a runner down we can get the ball down the outside.
“[For Salah’s first], [Jordan] Hendo takes the ball out the way and I’m able to play it into Bobby and we got the pen.
“That was the idea, to drag a centre-half out and not allow them to stay in and head the ball away.”
Mohamed Salah subsequently took advantage of the space on the right-hand side of the pitch to cause David Luiz plenty of problems.
The Egyptian scored a penalty after the Brazilian tugged his shirt and then curled a trademark effort past Bernd Leno to put the Reds 3-0 up.
Klopp’s side are now two points clear from Manchester City at the top of the Premier League after three games.
Liverpool face a trip to Burnley next weekend as they look to keep their 100 per cent record alive.
