#2 Flop: Stephan Lichtsteiner

Stephan Lichtsteiner was abysmal on the right side of Arsenal's defence as the former Juventus man was constantly harassed by the duo of Sadio Mane and Andrew Robertson.
Arsenal's right-back was at fault for the first goal as his attempted clearance bounced off Shkodran Mustafi which allowed Roberto Firmino to literally walk the ball into an empty net. There was no communication between Lichtsteiner and Mustafi, which led the Brazilian to equalize.
Lichtsteiner was also at fault for conceding Liverpool's third goal as he did not pay attention to Salah's run before the Egyptian assisted Sadio Mane. The outcome would have been better had the Swiss international been alert to Salah's run instead of being preoccupied with Virgil van Dijk.
There was no attacking threat offered by Lichtsteiner and he was also caught out of position on countless occasions which gave licence to the likes of Mane and Robertson to run riot down the left flank.
