Liverpool kept themselves firmly in the fight for the quadruple as they overcame a spirited Newcastle to keep up the pressure on Premier League leaders Manchester City.
Jurgen Klopp made five changes at St James' Park, including leaving top scorer Mohamed Salah on the bench, after the Champions League semi-final on Wednesday.
It looked like it would backfire as in-form Newcastle started strongly, pressing Liverpool high and forcing them into a couple of early mistakes.
But Liverpool grew into the game and were dominating possession when Naby Keita struck in the 19th minute.
The midfielder showed great composure as he dribbled across the box and past Martin Dubravka before slotting into the net.
