Ferrari has bolstered Kimi Raikkonen's engineering team in a bid to help the Finn move up the Formula 1 grid this year.
The 2007 F1 world champion has had a challenging start to the 2014 campaign, having struggled more than team-mate Fernando Alonso in getting comfortable with the feel of Ferrari's F14 T under braking and corner entry.
With more work to do to overcome Raikkonen's issues, Ferrari has decided to bring back its test team engineer David Lloyd to a racing role to help Raikkonen from this weekend's Canadian Grand Prix.
Lloyd will help support Raikkonen's race engineer Antonio Spagnolo and other staff in trying to improve the lines of communication between the Finn and the team so as to get a better understanding of what is needed.
Raikkonen has worked well with British engineers in the past, having had a long partnership with Mark Slade at previous teams McLaren and Lotus.
It is undecided yet if the change will be permanent, or will last only a few races until enough progress has been made.
Lloyd originally joined Ferrari from BAR in 2003 as a test engineer, before becoming race operations manager in 2007 after the departure of Nigel Stepney.
He then returned to a role as a test engineer for the Maranello outfit.
