Manchester City boss Manuel Pellegrini says no "revolution" is required ahead of this summer's transfer window.
The Citizens eased past Queens Park Rangers to open a three-point lead from Arsenal and keep their hopes of a top-two finish alive.
"I think this year we lost many points at home," Pellegrini told Sky Sports.
"But we have to finish the season the way we want to play. The desire the team reflects in this moment is very important for us.
"It's not easy for any team to win titles in a row in the Premier League because you have five teams who have the same power as our squad and money to spend. Of course I am sure next year we will be fighting again for the title.
"In the last four years this team won two Premier Leagues and finished second twice. We won the League Cup, the FA Cup, we must improve for the future but I never accept we are failing.
"It's not a revolution I think we need."
