Joe Schmidt will start a new position with rugby's governing body next month after stepping down as Ireland head coach last year.
Ireland can become Six Nations champions by winning their final two matches in the disrupted 2020 season, with Italy and France to come.
Six of the top seven teams in the world rankings will start life with a new coach following the Rugby World Cup.
Departing duo Joe Schmidt and Rory Best did a "wonderful job" for Ireland, according to New Zealand head coach Steve Hansen.
Ireland have struggled to hit the same heights in 2019 after their success last year, admitted outgoing head coach Joe Schmidt.
New Zealand will be ready for Ireland in the Rugby World Cup quarter-finals having been beaten in their last meeting, warns Joe Schmidt.
Ireland will not have Bundee Aki available for the rest of the Rugby World Cup after he was banned for three weeks.
Joe Schmidt is not optimistic Bundee Aki will avoid a ban but Samoa coach Steve Jackson wants a judiciary to "see some sense".
Ireland head coach Joe Schmidt said it was "hard to argue" with Bundee Aki's red card but was keen to see the incident again.
Joe Schmidt says Ireland must control their own destiny and will take Samoa seriously as they aim to book their place in the last eight.
