Caterham F1 rookie Marcus Ericsson is looking forward to this weekend's Belgian Grand Prix, and not just because Spa-Francorchamps is one of his favourite circuits.

The Swede, now eleven races into a difficult debut F1 campaign, is not alone in enjoying the Ardennes rollercoaster, but is more excited by the upgrades expected to appear on the CT05 this weekend.

New deputy team principal Manfredi Ravetto has already confirmed that part of the development push will see a new nose introduced alongside a number of other updates at Spa [ see separate story], despite the upheaval of last month's takeover by a consortium of Swiss and Middle Eastern investors.

"The new nose is part of a package of innovations we are bringing to Spa as a demonstration of how we are trying to revive our performance, even if we are restructuring the team and living difficult days from which we hope to emerge soon," Ravetto told Italy's Omnicorse, "The changes in Belgium are, in fact, just the beginning - the most important things you will see later."

Ericsson currently holds Caterham's best result of the season, after taking eleventh place in Monaco, but, with Marussia rival Jules Bianchi scoring points in the Principality, the Leafield-based squad remains mired at the foot of the constructors' table behind equally-scoreless Sauber. The Swede has already tasted success at Spa, having won there in GP2, but admits that, as well as looking forward to driving the spectacular circuit for the first time in an F1 car, he is anticipating a more competitive weekend with the new parts.

"We're aiming to make real progress in Belgium, and that will make the whole weekend even better for the team and for me," he confirmed "We haven't had new parts on the car for quite a while, so to be coming to a track like Spa with a package that gives us a chance to take a step forward, that's a good feeling.

"We're taking nothing for granted, however. We have a lot of work ahead of us to get the most out of that parts but everyone is prepared for that and if we achieve what we're setting out to, and have good reliability, it could be a really good weekend for us."
