It was an act of pure brilliance from runaway victor Marc Marquez after he passed the chequered flag at Assen, when he stretched his arms and legs wide and lay across the fuel tank of his machine to mimic the swimming breast-stroke. It was the most spectacular victory celebration ever seen on the circuit. Ducati rider Andrea Dovizioso was second and Marquez’s Honda Repsol team-mate Dani Pedrosa was third.
