Manchester City manager Sven-Goran Eriksson is only interested in buying top quality players in the January transfer window.
City have made their best start to a home campaign for 50 years and lie third in the table.
The Swedish coach told the Manchester Evening News: "I am told there is money available in January but how much I don't know yet.
"Before I get into lists of players in whom we might be interested I think it is vital to know what that spending figure will be.
"If we want to strengthen the squad then we have to be very clever about it.
"We must not buy average players. We have to buy top-class and for them to be better than we have already. That will cost a lot of money."
Eriksson added: "We have to compete reputation-wise with the big four who can offer Champions League football.
"But I am sure we are one of the teams that foreign players are looking at and thinking: 'I would like to play there.' And that is very good."
