Liuzzi to sit out Spa, too?

Christian Klien is likely to be given yet another grand prix – at Spa – in Red Bull's race seat before rival Vitantonio Liuzzi sees out the year.

22-year-old Klien, who has spent most of season '05 in the blue car, was recently confirmed alongside David Coulthard for Turkey and Monza.

But team boss Christian Horner hinted at the Italian circuit that, with the Belgian grand prix just a week away, one more is probable.

''This week we will make a decision,'' he told reporters.

''It would make sense, if Christian has a good weekend, that he continues in Spa, but it is almost certain that Tonio will drive again (in 2005).''

Even after the season finale, Klien and Italy's Liuzzi – who live together – will continue to argue about who is the best bet. With Scott Speed to steer the 'Friday' car in 2006, either could be shunted out of Red Bull altogether.
