World Champion Damon Hill denies being unhappy with the Arrows team. Hill said at the TWR factory today that despite having no finish yet this season he still believes in the team.

Hill commented: "I read a lot of reports from the races and they seem to give the impression that I am despondent, I'm unhappy, I'm dejected, and I'm cross. But it couldn't be further from the truth. I am very happy, I have got a lot of faith in Tom and the Arrows team. It's been a tough season, but I have been through tough seasons before and this is a great car in the early stages of development. These things are not going to happen overnight."

The main problem the Arrows team have is the reliability of the Yamaha engine. Team boss Tom Walkinshaw said he had a very serious talk with the manufacturer: "I have every faith that Yamaha will do everything that they possibly can to improve the reliability and performance of the engine."

Hill will be testing a revised version of the Spec C Yamaha engine next week. The location is classified.

Gerhard Berger is recovering at home, in Monaco, from surgery for an inflamed sinus.

Berger said: "I will rest for another week and then I hope to be in the best shape for the Canadian Grand Prix."
