Liuzzi and Red Bull

(GMM) Vitantonio Liuzzi declined to give much away when faced with speculation of an internal struggle to grab his talents for 2007.

It is rumored that the Italian, who this year is racing for 'Toro Rosso', is being courted by the junior squad's big brother Red Bull.

STR co-owner Gerhard Berger, however, has made it clear that he would like to keep the 24-year-old for another season.

''I just do my best for Red Bull overall,'' Liuzzi was quoted as saying by 'Racer' magazine.

Paired with rookie Scott Speed in 2006, 'Tonio' has been the standout so far and at Indianapolis snared the ex-Minardi team's first points in its new guise.

He explained: ''At the moment it's just important to get the best results for me and Toro Rosso, and for next year we'll see.''
