FA Cup: Aguero inspires Manchester City come back as Wigan defeat Crystal Palace

A hat-trick from striker Sergio Aguero spared Manchester City an embarrassing FA Cup exit as they came from 2-0 down at home to Watford to win 4-2 in the fourth round.

The Sky Bet Championship visitors, who had won just twice in their last 16 matches, sensed an upset after Fernando Forestieri and Troy Deeney gave them a half-time lead.

City manager Manuel Pellegrini's substitutions at the break saw defenders Vincent Kompany and Pablo Zabaleta sent on with forward Stefan Jovetic added in the 57th minute.

Within two minutes City pulled one back when Aguero converted Aleksandar Kolarov's cross and after the Argentina international doubled his tally Kolarov added a third three minutes from the end.

That still left enough time for Aguero to complete his hat-trick.

Goals in either half from Victor Moses and Daniel Sturridge were enough to see Liverpool overcome Bournemouth 2-0.

The visitors named a strong side for the game at the Goldsands Stadium and it was Luis Suarez who created both goals to see the Reds into the last 16.

Matty Fryatt scored both goals as the Tigers beat League 2 Southend 2-0, Guly Do Prado and Sam Gallagher scored in the Saints' 2-0 win at home to Yeovil while Frazier Campbell's solitary strike was enough for the Bluebirds to defeat Championship side Bolton 1-0 at the Reebok Stadium.
