Manchester City boss Sven Goran Eriksson has been told his winter market budget is limited to £10 million.
Eriksson said: "If you see all the players we have been linked with, we would be signing about 20 players. Some of the speculation might be true, but there's a lot of it and the reason is people think we have money.
"We're working on things and for sure, something will happen. We have signed Nery Castillo and we will be taking in at least one more player this month."
