Toyota have offered Finnish driver Kimi Raikkonen a deal for next season but the 2007 Formula One champion's management wants more.
Toyota's motorsport president John Howett says they don't play too many games, as they put on the table what they can afford and what they think is a serious offer in the current market.
Raikkonen will be replaced at Ferrari by double world champion Fernando Alonso at the end of the season and has yet to decide what to do next, although a return to his former employers McLaren appears his most likely option.
The party-loving Finn has said he wants to be in a competitive car, and Toyota have yet to win a race since they entered the sport in 2002.
Poland's Robert Kubica was another target for Toyota until he signed with Renault.
The Japanese team, whose future in the sport remains subject to considerable paddock speculation, currently have Italian Jarno Trulli and Germany's Timo Glock under contract.
