Meanwhile, Guardiola can reflect on a week in which his side scored 15 goals without reply ahead of four games in three different competitions over the next two weeks. The result of this match to be as, Watford 0-2 Manchester City.
But, with United not playing until tomorrow, City have a chance to leapfrog their local rivals. If Watford fold as readily as they did here on a regular basis, Silva might find himself facing a similar fate to his predecessor and Quique Sanchez Flores, who were both removed after a single season in charge.

Manchester City will travel to Vicarage Road to meet Watford and City manager Pep Guardiola showered praise on his opposite number Marco Silva in his pre-match press conference yesterday.

Crystal Palace became the first club in league history to lose its opening five games without scoring. They have to know - he has to know, the family has to know and especially the managers [Sancho's advisors] have to know - we had a lot of confidence in him.
