Roberto Mancini expects Manchester City to "spend a lot of money" this summer as they look to match Barcelona and Real Madrid.
It remains to be seen whether City will be reined in by UEFA's Financial Fair Play rules, with chairman Khaldoon al-Mubarak recently saying the club now "have a nucleus" and "are not starting from the same point as in other pre-seasons".
However, Sir Alex Ferguson has said he expects the new Premier League champions to pay out "stupid money and silly salaries" this summer, and it appears Mancini expects further investment to be made.
"Barcelona and Real Madrid every year buy two or three players and spend a lot of money," he told BBC Sport. "I think for Manchester City it will be the same. We need to improve. We need to have the strength to play Champions League and Premier League."
It would appear that any expenditure on improving the squad will not be offset by the departure of Carlos Tevez.
Tevez had gone AWOL for a substantial part of the season following a disagreement with Mancini during the Champions League group stage game at Bayern Munich in September, but the Argentine returned to help fire City to the title.
"It's not difficult to manage Tevez," Mancini said. "He's a good guy. We had a good relationship always. I don't know why we had that situation in September but in the end he's a good guy and a fantastic player."
