Ford (centre) played his part in Ireland's Triple Crown success

The ex-Great Britain rugby league scrum-half helped the Irish to their first Triple Crown since 1985 this year and will continue to work with them.

Saracens coach Rod Kafer said: "Mike has played a major role in Ireland's success over recent seasons. We're delighted he is joining us."

Ford said: "When I met Rod, we hit it off instantly. The club is very forward thinking and they have a good set-up."

Kafer added: "Mike will work on both defence and attack and he'll also work closely with the back line. His background in rugby league makes him well suited for this role."

Saracens have endured another wretched season but in the past two weeks have signed five new players - including England internationals Alex Sanderson and Dan Scarbrough.

Off the pitch, Ford will be the second fresh arrival after coach Steve Diamond was lured away from Sale Sharks.

The former Wigan star said: "With Steve also joining, there is a young coaching team at the club. Everyone at Saracens is ambitious - as am I."
