Berger told German magazine Auto Motor und Sport that both drivers lacked focus and spent too much time on ‘fun’. “You don’t see superstars like Schumacher and Alonso at too many parties,” he said. Berger has also denied that double champion Mika Hakkinen would make a surprise comeback to Formula 1 with STR in 2007.
Toro Rosso will probably announce their driver lineup at the beginning of next month. Although Speed and Liuzzi are the firm favourites, Sebastien Bourdais, Robert Doornbos and Ernesto Viso are also thought to be in the running.
