Lotus say they need both Grosjean and Raikkonen to score 'big points' in 2013

Eric Boullier has made clear that Romain Grosjean needs to claim his share of big results in 2013 if the team are to hit their stated target of breaking into the top three of the Constructors' Championship.

For his own part, Grosjean acknowledged his 2012 season had been blighted by too many controversial moments - but expressed optimism that he would be able to put that behind him this time round. "I think it's clear for everybody that we had a good qualifying speed but too many incidents, so that's what we're going to try and work on," the Frenchman told Sky's Craig Slater. "I'm confident, hopefully the car will be good - it looks very nice, which is always a good starting point - and we will try to make it as good as we can and try to improve myself every time I jump into the car."
