Manchester City will spend big on new signings club chairman Khaldoon al-Mubarak has confirmed.
City who won the Premier League title two weeks ago lost the Champions League final to Chelsea and that has prompted the club owners to hunt for new firepower.
"Having won the league, it is not the time to sit back and be content," said Khaldoon.
"That would be your biggest mistake. This is the time to send a strong message that there is no contentment, that you are not satisfied with just winning the league."
City are keen to sign Tottenham forward Harry Kane and have also set eyes on Erling Haaland of Borussia Dortmund.
The Cytizens have space for Kane in Pep Guardiola's squad following the departure of striker Sergio Aguero to Barcelona.
"Sergio Aguero's shoes are very hard shoes to fill but I am confident we will find the right player to fill those shoes," said Khaldoon.
"There are other areas in the team that need investment. Not too many - it is not about numbers, it is about quality. But we will bring quality into the squad in a couple of key positions."
"Our financial balance sheet is strong and we will invest wisely and do what we need to do," said Khaldoon.
"But the market will be difficult as there won't be enough liquidity. There will be movement but it will be done in a more creative way."
It has been suggested City might use players as bargaining chips to get deals done, although in the past, such transfers have proved difficult.
There have been speculations about Pep Guardiola's future at the club after the latest setback but Khaldoo says they are calm about the Spaniard's future at the Etihad.
"We will do everything we can to keep Pep for as long as possible at this club," said Khaldoon.
"He is in the right environment and has the right infrastructure around him.
"We have the greatest trust and the greatest relationship and we have achieved so much. The journey goes on and it will go on as long as Pep is happy and we are happy."
