Manager Slot, who watched the game from the stands as he started a two-match touchline ban, said: “I think what impressed me most was the mental strength in both games because after Everton and Wolves, maybe after Villa a bit, people started to question us a bit.
Yet even with just 10 games remaining, Slot is not thinking about the title just yet and is already looking ahead to next week’s Champions League clash against Paris St Germain.
Liverpool’s advantage has increased from seven points in the past week, thanks also to the dropping of five points by closest challengers Arsenal in their last two games.
The Merseysiders had looked nervy in games against Everton, Wolves and Aston Villa earlier this month but doubts seem to have been swept aside after confident wins over Manchester City and now the Magpies.
The defeat meant Newcastle lost ground in the battle for a Champions League spot, leaving them sixth, three points behind fourth-placed Manchester City.
