Ask Eddie Jones about the potential impact that Dr Sherylle Calder will have on his England squad and he directs you to a stunning try scored by South Africa’s legendary wing, Bryan Habana.

Habana’s moment of magic came in the 75th minute of the 2007 World Cup semi-final victory over Argentina in Paris, when he intercepted a pass from Juan Martín Hernández to Ignacio Corleto on South Africa’s 22-metre line. Habana’s timing is a thing of wonder. A fraction of a second later and Corleto would have had a run to the South African line. Instead, Habana races 80 metres upfield to score one of the tries of the tournament. It is worth a watch on YouTube.

The Australian says the spatial awareness that Habana displayed for that try was a direct result of his work with Calder, the sports scientist and performance coach who will today become the newest addition to England’s management team.

Of the tasks that Calder set Habana, one included catching a ball at different angles, heights and speeds, 118 times in a minute. He was also set eye exercises on his laptop, having identify different shapes and colours. Habana was the tournament’s top try scorer, with eight.
