Eddie Jones has added a new element to his England coaching staff with the appointment of Ian Peel as scrum coach.
Peel will leave his position as England U20s head coach to take up the part-time role with the senior squad while also joining Saracens on a permanent basis.
He said: “I have been coaching within the RFU pathway for the last six years so this is a huge chance to go and coach senior players at a quality club that performs at the highest level domestically and in Europe.
“I have no doubt it will be great environment to work in and there are a number of players who I have worked with within the England age-group set-up like Maro Itoje, George Kruis and Mako Vunipola.
“I am really looking forward to getting involved in the day-to-day and the hands-on coaching every week.”
On the chance to work with new England coach Jones, Peel said: “This is a huge opportunity and I am really looking forward to getting stuck in with lots of the guys who I have worked with through the age-group teams but also when I have gone in and helped Graham Rowntree over the last few seasons.
“It is a huge honour to go and deliver that for the seniors and joining up with Eddie, Steve Borthwick, Paul Gustard and the rest of the team.”
Peel's appointment at Saracens offsets the Aviva Premiership club's impending loss of Paul Gustard.
The RFU did not indicate if Peel's role would continue beyond the Six Nations which runs from February 6 to March 19.
The 39-year-old has been involved in the England U20s programme since 2013, firstly as an assistant coach, winning back-to-back Junior World Championship titles in 2013 and 2014 as well as reaching the final last year.
Jon Callard will head up the U20s programme for the 2016 Six Nations and will be assisted by forwards coach Peter Walton and backs coach Rory Teague, who will move from coaching with Saracens Academy to become an RFU International Performance Coach.
