Jurgen Klopp hailed the work-rate of Andy Robertson in Liverpool's 1-0 victory away to Newcastle.
Robertson put in a typically committed display as Liverpool returned to the top of the Premier League courtesy of a goal from Naby Keita.
The left-back was seen sprinting in the closing stages of the game, which delighted Klopp.
Klopp also spoke highly of the performances of Joe Gomez, James Milner and Diogo Jota, who all came into the team at St James' Park.
Speaking to BT Sport, Klopp said: 'The impact we have from the bench in games is outstanding but now it's really coming from the bench before a game, pretty much.
