On the result:
"It was very important to win, having made five changes," he told press. "We have to play so many games in January and it is very important to have the whole squad involved in what we are doing if we are to remain a competitive team in all of the competitions.
"I think it was important to score the first goal. When we are able to score the first goal, we know we are going to have more space.
"The two goals gave us more space as they've had to go for the draw. That allowed us to use that space and score two more.
"To have made so many changes but win the way we did is very useful."
On Fabian Delph:
"I'm very happy with his performance," he reflected. "He had bad luck at the start of the season with different injuries."He has settled down now and he makes a good work ethic and gives us good build up."
On Sergio Aguero:
"In the last game, he didn't score because [Tim] Howard made two beautiful saves," he added, "but he was making all the moves he normally does when he is 100% fit."
"In every game, he will continue to improve."
On Kelechi Iheanacho:
"Kelechi is a very important player," he said. "Every game he plays, he takes positively. Today, he had a great impact.
"I had to make the substitution because Aleks Kolarov was injured and we needed tall players for set pieces.
"He has a bright future at this football Club."
