LONDON, England - Drivers Lewis Hamilton and Nico Rosberg will remain paired at Mercedes for at least the next two years of Formula 1.That's the claim of boss and team co-owner Toto Wolff in response to a wave of speculation about the future of drivers at the currently dominant F1 outfit.Wolff had played down reports that Mercedes could be eyeing frustrated Ferrari driver Fernando Alonso, while Mercedes' Hamilton was this week spotted at Ferrari's Maranello HQ.'LONG-TERM CONTRACT'Nico Rosberg's place with the Silver Arrows was also in doubt until team figures declared the 28-year-old German had a "long-term" contract. Hamilton is also contracted to Mercedes, Wolff told a group of Spanish reporters at the team's UK factory."Our drivers have contracts for two years, so we cannot consider any possibility," Wolff was quoted as saying by Marco Canseco, a correspondent for the Spanish sports daily Marca. When asked about Alonso, Wolff answered: "Everybody knows he is one of the best drivers on the grid and one that fits with what Mercedes wants."But we already have two of the best."Stay with Wheels24 for the 2014 F1 season – fresh reports every day.
