Williams rookie Valtteri Bottas believes he has held his own in his team-mate tussle with Pastor Maldonado.
Both Williams drivers are yet to score any point so far this campaign, but Bottas has outqualified his team-mate in four of the six races. He has also finished ahead of Maldonado four times, but the Venezuelan retired in three of those races.
"I think my performances relative to Pastor have been pretty good. Pastor is experienced - it's already his third year at Williams - and I would say that I match him more-or-less," he told the official Formula One website.
"I can't really point at one particular thing that I've learned from him, but of course you pick up things, especially at a track like Monaco that I didn't know before this season. I was reading his data very carefully to see how he was doing it."
The 23-year-old Bottas has been part of the Williams team for several years and he spent the past two seasons as the official reserve driver, something which he thinks has helped him a lot in his debut campaign.
"I am very pleased with how things have gone in terms of my transition from test driver to race driver," he said. Being the third man was a good platform to improve and develop, especially when I got the Friday running last year. That was a perfect preparation for my debut season. I have to give big thanks to Williams for making it possible as I felt really ready to race in Melbourne.
"I think that, as a team, Williams see the talent in me; that I really can be something very good in the future. In the years I've been with Williams I've developed hugely - and of course I have inhaled the team culture."
