Toyota team boss John Howett has said there is a strong probability that Jarno Trulli will not remain with the Japanese team next season, hinting that there is a difference of opinion over money.

"We are in negotiation and we haven't reached an agreement," Howett told reporters in Valencia, "and there is a possibility that we won't close the gap. At the moment the gap is reasonably large

"We have to say," he added, "that there is a very strong probability not to renew."

Trulli, who is now in his sixth season with the Cologne based outfit, admitted that he is in discussion with other teams, but denied that the situation with Toyota is about money.

"Money has never been an issue, absolutely not," he said. "At the moment there is a lot of cost cutting and I do believe in this part also the driver has to play his role and I am more than happy to.

"We are talking," he said of Toyota, "but nothing is really sure or clear so I think we need to wait a little bit more.

"I am waiting to talk with some teams," he admitted. "With others we are in talks but the priority is understanding first of all what Toyota does and wants to do."

With the departure of BMW, three new team entering the sport, uncertainty over Kimi Raikkonen remaining in F1 and Fernando Alonso almost certainly heading to Ferrari, the annual game of 'musical chairs' will be a little more frantic than usual this year, consequently some teams, and drivers, may opt for a waiting game.

"I think looking at the way the drivers' market is moving we have all got to hold our breath a bit and see what happens," said Howett. "There are a lot of drivers who are talking to everybody at the moment.

"It seems that the Ferrari position with Kimi could then create other opportunities or close them for others," he added, "it's one of those situations where as soon as one moves it becomes fairly clear."

Asked about the future of Timo Glock, who, following a strong start to the year, has appeared to 'drop off' in recent races, Howett said: "With Timo we have the contract to our advantage. I think there is a high probability we will renew but we have asked him to try and look at his qualifying.

"In races he is phenomenal," added the Englishman, "I think he was second quickest from our analysis in Hungary so the race pace is there, the car certainly can work extremely competitively."
