Felipe Nasr will work with a new engineer for the remainder of the 2015 Formula 1 World Championship season after a 'mutual agreement'♏ to part ways with Craig Gardiner.

The Brazilian has been working with Gardiner since making his F1 debut with Sau💮ber earlier this year, but differences of opinio🍰n behind the scenes have prompted a reshuffle in the team, with Paul Russell taking on his duties.

Nasr has already agreed a ne💞w deal with Sauber for the 2016 season, with Russell - who has worked with Pedro de la Rosa in the past - set to stay on board.

"Paul has been on the team for a long time and I worked with him in the pre-season tests in Jerez and Barcelona, and also after the Austrian GP. He's a guy with whom I have a good relationship and for knows the team. I think he will be a good news. He worked ཧꩲwith Pedro de la Rosa for a while, I think in 2009 and 2010, and our goal is to work as well as possible to score the maximum possible points.

This change was a mutual decision. We decided this together - myself and the team, and the important thing is that our goal is the same. Paul assumes this role from this weekend to help the team as 🌠much as possible."

After grabbing the headlines on his debut with a run to fifth pla🙈ce in Australia, Nasr has cracked the top ten on just three further occasions, even if he remains classif🐓ied ahead of Pastor Maldonado, Carlos Sainz and team-mate Marcus Ericsson.
