West Ham United boss Sam Allardyce feels Brendan Rodgers needs to rotate his squad more.
The Hammers thumped Liverpool on Saturday at the end of Champions League week.
Coupled with the Europa League campaign two seasons ago, Rodgers has now won just three of 12 games he has played following European fixtures.
When Allardyce was at Bolton, his record post-UEFA Cup games was five wins out of seven.
He said: "For me it was good to see that for Liverpool there was most of the team that was out there on Tuesday. And they had an unusually difficult game beating the opposition they had on Tuesday night.
"Maybe that left them a little jaded, who knows. But when you get into the game as quick as we did today, it really caught them by surprise.
"It's not impossible to stop it. When I spoke to Sir Alex, who is the master at it, he was the first man to start rotation 20 years ago, he just said you need two teams."
