Timo Glock says he has fears over the uncertainty surrounding Toyota’s future plans in Formula 1.

Toyota has an option on Glock’s contract for next year, which they were expected to take up, but thus far have failed to do so. This comes soon after fresh rumours surfaced about Toyota following BMW out of the sport at the end of the season, with Toyota HQ in Japan yet to set any funding for the team next year.

Glock says he hopes to stay on with Toyota for another year, but when asked if he was worried about the recent speculation about Toyota withdrawing, he replied; “A little bit, yes.”

“It is a bit of a worry at the moment and if you look at the situation with BMW – I think that all of the manufacturers are in a difficult situation.”

Glock also said he has been considering other options for 2010 if Toyota fails to take up a contract extension with him.

For me, it’s not an easy situation. You have to look at what options you could have if it goes wrong. But hopefully everything goes as we planned it and I can stay at Toyota.”

Jarno Trulli has also been at loggerheads with Toyota management over renewing his contract with the team, with a reputed 50% pay cut which Trulli was willing to take, however the issue appears to relate to contract length. Trulli is thought to have wanted a two year deal, but with Toyota offering him a single year deal only.
