Liverpool manager Jurgen Klopp has credited set-piece coach Pete Krawietz for Roberto Firmino's goal against Inter Milan on Wednesday.
Andy Robertson's corner was turned in at the far post thanks to a glancing header from Firmino.
And Klopp says the move was straight from the training ground.
Asked whether his team had worked on the set-piece for the first goal, Klopp said: "Yes. Pete Krawietz and our analysts are responsible for that.
"When we do the analysis, we obviously see how the opponent is defending – everybody is doing that – and we didn't have a lot of time to train, but yes we trained set-pieces yesterday.
"That was the only proper thing we did in training; a bit of tactical stuff, but without intensity and set-pieces you cannot train without intensity because one has to shoot and the other guys have to run. So, yes, it's all credit to Pete and his boys."
