Fiat has received several firm offers for some of the 3 billion euros ($US2.6 billion) in assets it wants to sell to help reduce its debt, the Financial Times (FT) said, citing chief executive Paolo Cantarella. The planned assets sale is key to a restructuring plan announced last December, which is meant to halve Fiat's net debt of six billion euros and to help turn round its automotive business, the FT said.
