After winning their opening two games of the season, the Gunners slipped to a 3-1 defeat at Anfield with Mohamed Salah producing a sparkling display for the hosts.

Despite the scoreline, Emery insisted his side had ‘reduced the distance to Liverpool’ but Cascarino insists Arsenal still have lots of work to do if they are to threaten Jurgen Klopp’s men and Manchester City at the top of the table.

“Arsenal have improved under Unai Emery but tactically he got it all wrong against Liverpool on Saturday,” wrote Cascarino in his Times column.

“Firstly, if you don’t know that Liverpool’s full backs are a threat then you’ve been living on the moon for the past year.

“Trent Alexander-Arnold and Andrew Robertson had so much time on the ball. Secondly, Roberto Firmino must have dropped into midfield 20 or 30 times and there was no one taking responsibility for picking him up.

“He’s so vital for Liverpool, he must be shackled to stop them. And finally I don’t think you can play a back four with David Luiz — watching him one-on-one with Mohamed Salah was laughable.

“Emery spent £135 million this summer and they may be better but still looked naive and limited in terms of shape and system. They are still a long way off the top two.”
