Monaco GP: Lotus's Romain Grosjean penalised for shunt
Lotus driver Romain Grosjean has been given a 10-place grid penalty at the next race in Canada for causing a crash in the Monaco Grand Prix.
Grosjean, who last year served a one-race ban for the most serious of a series of crashes, had four accidents in three days in Monaco.
The final one was a rear-end collision with Toro Rosso's Daniel Ricciardo.
Grosjean's team boss Eric Boullier said he would talk to the Frenchman to try to resolve his problems.
"We need to cool him down and have a proper discussion when he is back in the factory," Boullier said.
Grosjean crashed twice in very similar fashion at the Sainte Devote corner during practice in Monaco and also punctured a rear tyre when misjudging the chicane.
After a troubled 2012, in which he was quick but accident-prone, Grosjean has had a more measured start to the 2013 campaign, although he has lost some of the pace he showed last season.
In Monaco, he was fast throughout, but also on the verge of being out of control.
Boullier said Grosjean needed to "keep the pace and make sure he is back under control".
Asked if it was a worry that Grosjean could not seem to find the balance between pace and control, Boullier said: "No it is not a worry.
"He did a great job over the winter and fixed all the problems he had last year so it is just, you know, some frustrations when he knows he can be fast and he just needs to build himself, saying he is fast and he can deliver some big results.
"He did it in Bahrain where he finished third, and he was on the way to do it in Barcelona so it is just not losing the momentum and knowing he is back on track with the real expectation."
Boullier blamed the accident in the race on Grosjean's frustration at being bottled up behind Ricciardo.
It was being held up behind the Australian in qualifying that left Grosjean 13th on the grid when he was expecting to qualify in the top four.
Boullier said: "He had the pace, we could see it. It's even more frustrating because of that. The Thursday accident at Sainte Devote didn't help but it happened. Building up his frustration was again Ricciardo, who didn't allow him to complete the Q2 like he should have done. He ended up 13th on the grid."
Grosjean is on a probationary contract which is reviewed every three races - and Monaco was the sixth of the season.
Asked if he had considered standing Grosjean down for a race in favour of test driver Davide Valsecchi, Boullier said: "Not yet."
