Dani Ceballos has revealed he was stunned by how good Liverpool were during Arsenal's 3-1 loss to the Champions League holders in late August.
The Gunners have been tipped by many to finally break back into the Premier League's top four this season after a few years away from Europe's elite club competition, but were given a quick reminder of the gap in quality between the likes of Liverpool and Manchester City and those scrapping for European qualification during a chastening loss on Merseyside.
While Arsenal did claw one back through Lucas Torreira in the 85th minute, Ceballos admitted the team he faced last month is one of the best he has ever seen.
