Ducati's red-hot Marc Marquez won the Argentina Grand Prix on Sunday after trailing his brother Alex of Gresini Racing for much of the race as the pair finished in the top two yet again, while VR46 Racing's Franco Morbidelli was third.

After being beaten by his older brother for a fourth race in a row questions have been asked about Alex Marquez's respect for Marc Marquez.

Alex Marquez led much of the way in Argentina, but ultimately had to give best to brother Marc who now has four wins from four races (two sprints and two grands prix) this year
