Toro Rosso needs ‘good second driver’ – Berger
The Faenza based team has confirmed the Swiss youngster for 2010, but although the Spanish rookie is expected to secure the second seat, Jamie Alguersuari is yet to have his own extended contract officially announced.
Berger, formerly also a ten-time grand prix winner with prestige teams including Ferrari and McLaren, said the selection of Buemi's teammate this year is crucial.
"The possibility of great success with this team does exist," 50-year-old Berger, a close friend of team owner Dietrich Mateschitz, said in an interview with Germany's Auto Motor und Sport.
"We showed that (potential) in 2008 with Vettel. It depends on the drivers," Berger added. "Buemi is a talent, but Toro Rosso needs a good second driver, otherwise they could trip up."
