Oct.3 (GMM/Inautonews.com) Gerhard Berger has criticised the latest high-profile appointments by Mercedes’ formula one team.

With Renault’s former chief Bob Bell already on board, the Brackley based team announced last Friday that Geoff Willis and Aldo Costa will start their new roles in November and December respectively.

Willis was leading HRT’s technical team until very recently, while Italian Costa was ousted by Ferrari earlier this season.

Former F1 winner, joint BMW motor sport director and Toro Rosso co-owner Berger questioned the appointments, which are the latest in a recruitment push by the works Mercedes team.

“It looks to me as though Mercedes are shooting with a shotgun in the hope of landing a hit,” the Austrian told Auto Bild Motorsport.

Italy’s Autosprint magazine, meanwhile, wondered if it is “credible that, to strengthen his technical staff, Ross Brawn turns to someone considered a loser by Ferrari?

“Frankly, it’s not,” the report concluded.
