Gerhard Berger has backed Toro Rosso's decision to replace both Jaime Alguersuari and Sebastien Buemi for the 2012 F1 season.
Berger, who previously owned half of the team alongside Red Bull boss Dietrich Mateschitz before selling his share back to the businessman, insisted that the decision was the right one to take despite being 'hard' for all concerned.
Speaking with Motorsport-Total
, Berger argued that neither Alguersuari or Buemi had shown themselves to be good enough to possibly replace Mark Webber or Sebastian Vettel if either were to leave Red Bull – leaving the drinks company to explore other options as it looks to the future for its title winning team.
“I think it's correct, although it is very hard," he said. "For the drivers it's always hard, but for Red Bull and Toro Rosso, it's about preparing drivers - ideally from the Red Bull-pool.
"They need to find one that will eventually be the successor of Mark Webber or Sebastian Vettel when they move on. The demand for Red Bull is the highest, as we know, and the two (Buemi and Alguersuari) are at most average."
Berger added that he was particularly looking forward to seeing what World Series by Renault runner-up Jean-Eric Vergne - who will now partner Daniel Ricciardo in the new look line-up - is capable of.
"I've heard a lot of good things about the young Frenchman - maybe he's a new Sebastian Vettel," he added. "You have to try it, otherwise you do not know."
