Benefits clear to see for Jones as visual awareness coach joins England

Updated: 

Eddie Jones believes the hiring of visual awareness coach Dr Sherylle Calder will "add an edge" to England's preparation for the Six Nations.

England confirmed on Friday that Calder, who has aided two Rugby World Cup winners, will work with the team on a consultancy basis.

Explaining the addition to his backroom staff, Jones said: "2017 for us is about building really strong foundations for the team and making sure our fundamental skills are improving.

"Part of that is hand-eye co-ordination and our ability to handle the ball adroitly - Dr Sherylle Calder is an expert in that field.

"She has won two gold medals, 2003 with England and 2007 with South Africa, I used her extensively when I coached in Japan and had success with her then.

"I think she is really going to add an edge to the players' preparation."

England's squad for the Six Nations was announced on Friday, with James Haskell, Maro Itoje, Anthony Watson and Jack Nowell back in the fold following their respective injury lay-offs.

The reigning champions begin their campaign against France on February 4.
