Aston Villa 0 - 4 Man City: Kelechi Iheanacho hat trick sees Pellegrini's men into FA Cup fifth round
Manchester City are through to the fifth round of the FA Cup after a comfortable 4 - 0 away win over Aston Villa.
It was Kelechi Iheanacho's hat trick which secured Pellegrini's men the win at Villa Park on Saturday.
The first came just four minutes into the first half, before a second from the penalty spot.
But his third came in the second half after 74 minutes.
That was followed by a fourth goal from Raheem Sterling just two minutes later.
Heading into Saturday's fourth round match, boss Manuel Pellegrini has challenged his squad to fill the void left by Kevin De Bruyne's injury.
The inspirational De Bruyne faces up to 10 weeks on the sidelines after suffering knee and ankle ligament damage in Wednesday's Capital One Cup semi-final victory over Everton.
The 24-year-old had made a big impact after coming off the bench in that game, scoring and setting up another goal for Sergio Aguero.
This is typical of the impression he has made since his £54million club record signing from Wolfsburg last summer, having now scored 12 goals and assisted 12 others.
