Former Saracens head coach Andy Farrell has claimed that he is "massively excited" for England's future following his decision to sign a contract with the national side.

The 37-year-old, who joined England on a temporary basis for the Six Nations tournament, signed a three-and-a-half-year deal following his departure from Saracens earlier this month.

"I have watched England in South Africa and I am massively excited about the potential that was clearly evident in the three Tests and midweek matches," said Farrell.

"I had seven very special years with Saracens and the club will always have a fond place in my heart. I am grateful for the help they have given me as a player and a coach and I wish everyone involved the best in the future."

England head coach Stuart Lancaster added: "I am delighted that we have got Andy on board. He is a special coach and an individual and the way this team has developed is a testament to the foundations that we laid in the Six Nations.

"Andy, Graham [Rowntree] and myself work well together and I am looking forward to carrying on that close relationship over the next three-and-a-half years as we build towards a home World Cup."

Farrell will officially rejoin the set-up on July 2.
