The Gunners were beaten 3-2 by the Blues on Saturday , fighting back from 2-0 down only to be struck down by a late Marcos Alonso winner.
A pulsating encounter was characterised by a number of defensive errors from both sides, but Redknapp feels there is a clear skill gap between the two London sides.
Writing in his Daily Mail column, he said: “Arsenal may have shown fight to battle back against Chelsea but their 3-2 loss only papers over the cracks.
“Looking at the Arsenal team, not one of their players would get in Maurizio Sarri’s best XI. At the heart of defence, Shkodran Mustafi and Sokratis don’t look a partnership.
“At full back, Cesar Azpilicueta is both more solid defensively and more creative in attack than Hector Bellerin while Marcos Alonso has been impressive since his debut in 2016.
“Kepa Arrizabalaga could have done better with Henrikh Mkhitaryan’s first goal but I would rather have a young goalkeeper who is confident playing out from the back than Petr Cech, who is struggling. There was no contest between the two midfield enforcers.”
Arsenal have yet to win a Premier League game under Unai Emery, first losing to Manchester City before their defeat to the Blues, with the Gunners having suffered their worst start to a domestic campaign for 26 years.
Chelsea, meanwhile, have six points from a possible six after a first weekend win over Huddersfield Town ahead of a visit to Newcastle on Sunday.
