Jurgen Klopp expects Mohamed Salah's pace and finishing ability to add an extra dimension to Liverpool's attack in 2017-18.
Salah sealed club-record move to Anfield from Roma for an initial fee of EUR42million that could eventually rise to EUR50m.
Liverpool secured a fourth-place finish in the Premier League last season - something they might have improved upon considerably without a mid-season slump in January and February - and Klopp believes the Egypt winger will bring valuable cutting edge.
"Even if people didn't know too much about him, they [must have] watched a few videos and they are impressive," the former Borussia Dortmund boss told Liverpool's official website.
"We have had a few talks of course, spoke to each other - he is a really nice lad. He is really looking forward to coming to Liverpool and joining us.
"He is a fantastic player, with speed. We said after last season, there are a few things we would try to involve in an already really good squad; one of the things is speed, being kind of a finisher, preparing chances, making goals and all that stuff. He brings all this in.
"He is a naturally fit boy - he can run as quick and as long as he wants. That's all good. I'm really looking forward to [working with him]."
