Liverpool manager Jurgen Klopp says fatigue was the reason why he made seven changes to the side that drew the mid-week game in Dortmund.
The Reds produced a very convincing performance to ease past Stoke City by 4-1.
The win moves Liverpool closer to the Top Four in a weekend that saw Manchester United and West Ham United dropping points.
"Today, I'm really proud," Klopp told BBC Sport.
"We made changes and it was a completely new formation. I'm sure the players have never played together before in this line-up.
"We had to rest players today. We needed fresh legs. We needed to be greedy and not think a single per cent about it being another game. I'm really happy.
"Stoke played 70 to 80% long balls to Peter Crouch, and you have to be tuned into that. We were quickly tuned after a half-session on the training ground yesterday. It was a smart performance.
"Divock [Origi] is still a young lad. We have to be patient.
"He can play together with Daniel [Sturridge]. There's absolutely no doubt about that. We hope it stays like this that we have two strikers available like this because we have a big number of games to go."
