Marussia F1 has made a couple of personnel moves designed to improve its performance ahead of the opening European leg of the 2014 season.

With former race engineer Paul Davison stepping up to the role of head of vehicle performance, the Banbury-based team has announced the arrival of Francesco Nenci as Jules Bianchi's new race engineer.

Davison held the position of race engineer from 2012, working with Charles Pic before Bianchi's arrival in 2013. He continued to engineer the Frenchman's car for the opening part of the 2014 season pending Nenci's arrival from the Sauber earlier this week.

The pair will work together at this weekend's Spanish Grand Prix to ease the handover, before Davison focuses on his new role - which will be based at the Marussia Technical Centre in the UK - and Bianchi may be glad of the extra attention following F1's decision not to use the Circuit de Catalunya for pre-season testing.

"The first four circuits we have visited have all been quite different, and not so typical of the more traditional circuits we find on the European calendar, so it is always nice to get back to venues like Barcelona which we are a little more familiar with," the Frenchman noted, "This helps in terms of understanding the car a bit more but, having said that, this is not such a straightforward circuit as it's quite bumpy and quite challenging to find a good set-up.

"Generally though, if we can get the car working well here, it is a good sign, especially with our new developments. It has been nice to have a break and take some time to consider the opening races, but now I am excited to get my teeth into the next phase of the season."
