Arsenal midfielder Dani Ceballos admits he was blown away facing Liverpool last month.
On-loan Real Madrid ace Ceballos is only four games in and the third of those matches, against Liverpool, was a reminder of how high the bar has been set in this Premier League.
"I had never seen anything like it," he told the Daily Mail.
"I've not seen up until now a team that plays better, that presses better. That game had quite an impact on me.
"They suck the air out of you. You spend so much time defending and when you want to catch your breath and get on the ball for a bit, they've taken it from you again.
"I think Jurgen [Klopp] now has the team he first had in mind when he started four years ago."
