Alonso had the same reputation after 2007, he came off looking like he gives no respect, but he changed it in 2008.
Always the first person to congratulate new time winners after their victory(see Kubica at montreal and Vettel at Monza, Both times Alonso wasn't on the podium and came to them), this is something Vettel has to start doing to atleast start rebuilding his image I would say(you could argue that no one new is winning so how could he do this, but honestly could you see Vettel doing it unless he was already on the podium), that or leave redbull which I doubt he would do and anyone in the same position.
