Meanwhile, Schumacher has defended Lewis Hamilton as well as his father and says their hard work should be recognised rather than the cars they have driven.
“When we look at a champion dominating an entire era there is a risk of overlooking something important. The enormous amount of work it requires, how relevant are the resources, energy and talent applied by that champion who then wins,” he told Corriere Della Sera Sport.
“This is as true for Hamilton as it is for my father. There is nothing random about a great success.
“It’s an iceberg, and we often only see the tip of that iceberg emerging from the water.”
