Manchester City boss Manuel Pellegrini has warned his rivals for silverware the best is yet to come from Sergio Aguero.

The Argentine superstar was too good for Norwich City in a 3-0 FA Cup third round cruise at Carrow Road in scoring one sublime solo goal and setting up another for Kelechi Iheanacho. Aguero is still working his way back to full fitness after a six-week layoff with a heel injury but Pellegrini can see signs of the old predator.

'We know he is a top player and when he continues playing he will arrive at his normal performance,' said the Chilean. 'When you have players as important as Sergio it is very important for their team-mates, for the manager, for the fans to see them playing every game because he is a player that makes a difference. When 'Kun' continues playing games and playing more minutes, his performance always improves after he comes back from a long injury. Maybe in the first game back he didn't play so well. Last game against Everton he made a lot of better moments and here he continued making those moments and scored a beautiful goal. I am very happy about Sergio and I am very happy with the whole squad.'

Aguero will be a key figure in the push for an improbable quadruple.

'It's very important to be focused game by game, we've played in the FA Cup and now we must return to the Premier League,' said Pellegrini.

'We are in the semi-finals of the Capital One Cup, three points off the lead in the league, we have qualified in the Champions League and we have started on the right foot in the FA Cup.

'We have to play two league games at home and it's very important that we try to reduce the gap that we have with Arsenal.

'We have so many games to play in January that it is important to have the whole squad fit but, for the moment, we chose this team and they played very well and now we must choose which is the best team to start against Everton. We had a lot of criticism recently about how we have played away from home but I have said I am happy.

'We have tried to go for the three points, to play attractive football and I think the fans enjoy our football. We have demonstrated who plays in the team isn't the important thing if the style and the mentality is the same.'
