Tim Cahill believes Mikel Arteta has been inspired by Liverpool's full-back system to play a similar way with Arsenal.
The Gunners suffered a disappointing 1-0 defeat to Leicester City on Sunday but did have periods of promising play, including a controversially disallowed goal.
Speaking on Match of the Day, Arteta's former Everton teammate Cahill says he has been impressed with how adaptable the Arsenal boss is.
Pointing to Jamie Vardy's first-half absence for Leicester, Cahill said that Arteta appeared to change the Gunners' gameplan by pushing Kieran Tierney and Hector Bellerin high up the pitch in a similar way to Liverpool's full-backs.
"Mikel is really clever," he said. "The way he played in that first half, there is no Vardy, look how high their centre-backs are up.
"Look at how high the wing-backs are, it’s like Liverpool with Robertson and Trent Alexander-Arnold.
"It’s like what Mikel said in the last game about not scoring, but if Lacazette had scored the header, it would have been a different game because Leicester would have been chasing."
Arsenal could yet keep the same formation for their Premier League clash against Manchester United at Old Trafford next weekend, however Cahill said there is still work to be done after the Gunners fell to defeat.
Analysing Vardy's winning goal, Cahill felt Arsenal's defence failed to pressurise Leicester, which allowed space to create the chance to score.
He said: "The Arsenal defenders are now wary and it makes it easier for players like Harvey Barnes to attack.
"There were warning signs. There’s no pressure from the Arsenal defenders. Tielemans already knows, he finds the pass, it’s a great cross and a great finish.
"This was a disciplined performance from Leicester and Brendan Rodgers will be so happy because they have soaked the pressure up and they got the reward in the end."
