Pellegrini: City not failing

City put six goals past QPR on Sunday??to mathematically assure qualification for the Champions League, but last season???s title winners have fallen short on all four trophy fronts.

Despite criticism of a lack of progression under Pellegrini, the Chilean says the club must continue with the current personality and desire.

Pellegrini told Sky Sports: ???I don’t think we need a revolution, last year we won two titles. I never can accept that this team is failing, because I don’t think it is easy to win the title in the Premier League.

???It is important to continue with this period, personality and desire. This year we lost many, many points, especially at home against not so strong teams.

???It’s not easy for any team to win titles in a row because you have five very strong teams which have the same powerful squads and the same money to spend.???

City relegated QPR with the thumping 6-0 win at the Etihad Stadium, helped by a hat-trick from Sergio Aguero, who is currently leading the Premier League scoring charts with 25 goals.

Pellegrini insists the Argentine striker has improved his work-rate, and is wanting the ball more.

???For Kun [Aguero] it is very important for him to score, he wants to win the top scorer for the season.

???But also the way Kun is playing, he is working more, moving more and receiving more balls.

???I am very pleased because we play a complete game, not only because we score six goals, but also we keep a clean sheet against a team that take risks to try to play with two strikers.???
