Jurgen Klopp explained that Mohamed Salah's "unbelievable workload" was behind the decision to substitute him as Liverpool lost 3-2 at Arsenal.
The Egypt winger endured a frustrating afternoon at the Emirates as the Reds slumped to their second Premier League defeat of the campaign and was replaced for Fabinho with a little over 20 minutes left in north London.
Klopp said he was concerned with overworking his No.11 who came off around five minutes before Bukayo Saka scored the winning goal from the penalty spot to take Mikel Arteta's men back to the top of the table.
