Sauber hits out at error-prone Grosjean

Romain Grosjean would not be the most welcome face in the Sauber motor home.

Recently after the Spanish grand prix, Swiss newspaper Blick quoted Sergio Perez as cursing "f***ing French!" after a collision with Lotus’ Grosjean.

Then, at Monaco, Kamui Kobayashi had to retire with suspension damage after his spectacular high-flying crash at the first corner.

"Unfortunately it was Grosjean again," Peter Sauber thundered. "First Perez was the victim, now Kobayashi."

And those tangles were not reigning GP2 champion Grosjean’s only mistakes so far in 2012, despite demonstrating otherwise strong pace in his second season since his abortive 2009 debut.

Team boss Eric Boullier insists he is being patient with the 26-year-old.

"He is still early in his career and therefore has the right to make mistakes," the Frenchman is quoted by L’Equipe sports newspaper.

"This is no excuse, but all the drivers around him have done thousands of kilometres of testing and many races. He is still in his first year and I think has done a pretty amazing job for a rookie."
