BARCELONA (Reuters) - Formula One champion Nico Rosberg returned to the paddock on Wednesday for the first time since his retirement and said he had absolutely no regrets about his decision to quit at the top.
With Finnish replacement Valtteri Bottas putting the Mercedes through its paces on the third day of pre-season testing, Rosberg said the new cars looked 'monstrous' and a real physical challenge.
