Manchester City are through to the fifth round of the FA Cup.
But they gave their fans a big scare along the way, as they trailed Watford 2-nil at half time at the Etihad Stadium.
It looked as though a shock was on the cards, before a Sergio Aguero hatrick and another goal from Aleksander Kolarov in the final half an hour secured a 4-2 win.
Joining them in the fifth round are Liverpool, who comfortably beat Bournemouth 2-nil win away.
Elsewhere, holders Wigan Athletic beat Premier League side Crystal Palace 2-1 at the DW Stadium, Swansea beat Birmingham City 2-1 away from home and Cardiff City won 1-nil away to Bolton Wanderers.
And Sunderland avoided a big upset in the fourth round of the FA Cup.
The Premier League strugglers got past non-league Kidderminster Harriers 1-0 at the Stadium of Light.
