Sebastian Vettel has knocked back an invitation from Nico Rosberg to visit the Mercedes garage this weekend , fearing a PR stunt . Ferrari star Vettel and Mercedes ace Nico Rosberg became involved in a spat during the post-Australian Grand Prix press conference . It resulted in Vettel suggesting Mercedes should open up their garage at the Sepang International Circuit for an inspection of their cars in the wake of a dominant display at Melbourne 's Albert Park . Sebastian Vettel , speaking ahead of the Malaysian Grand Prix , has snubbed an invite from Nico Rosberg . Vettel branded Rosberg 's invitation to visit the Mercedes garage in Malaysia as 'staged ' and a 'PR stunt ' Rosberg then invited Vettel , with the latter suggesting the debrief in the engineers ' room for his visit . Now , however , such a plan has been knocked down as Vettel said : 'When I was joking with Nico in the press conference the deal was the invite was for all the paddock . Now it seems the invite has shrunk to just me . 'Initially I think it was called off by Niki ( Lauda , Mercedes non-executive director ) and Toto ( Wolff , Mercedes motorsport boss ) . Rosberg finished second behind race-winner Lewis Hamilton at the season-opening Australian Grand Prix . 'Now they 've told ( Rosberg ) yes , so I think they are using it as a bit more of a PR thing rather than a proper invite , so the answer is no I wo n't be going . ' Asked as to whether it was his decision or that of Ferrari , he said : 'It was n't really discussed to be honest . 'Initially it was called off and then I think they tried to use it as `` Ah yeah , we are so friendly and open to everyone '' . 'Even if I went there , do you think they would really open up ? That means I wo n't go , because even if I go it 's all staged . '
