Liverpool boss Jurgen Klopp confirmed assistants Zeljko Buvac and Peter Krawietz were making checks on Hoffenheim on Saturday.
The Reds will face Hoffenheim in their Champions League qualifier.
“Yes, they are in Hoffenheim," Klopp told Liverpoolfc.com at Aviva Stadium.
“They watched [Hoffenheim v] Bologna but after 20 minutes it was 2-0 Hoffenheim and after 25 minutes there was a red card for Bologna. That's more or less a waste of time!
“But it makes sense that they go there and see the team – they are really good."
