Renault boss Eric Boullier has played down rumours that the team could be the latest in F1 to run into financial issues.

Reports have suggested that the team approached Bernie Ecclestone's Formula One Management group in an effort to receive a commercial payment due at the end of the season ahead of schedule, although that request was vetoed by other teams on the grid.

Auto Motor und Sport suggested that the request from the team was down to the fact that a number of sponsorship deals haven't delivered the expected amount of money, but Boullier insisted there was no financial problems and that the team was suffering from a temporary cash-flow issue delaying its development work.

""These are the usual games played by people who try to tarnish your image," Boullier told the French news agency AFP. "There is nothing to say. There is no problem.

"I need to spend more because we want to finish the R30 and begin the R31. Like any normal company, I asked the shareholders to help us. We have television money that is coming, so why not ask for it in advance?

"We have signed three sponsors for the car and there are two more coming. Give us time. You don't sign a contract and the money comes the next morning. That's all."
