Sir Clive Woodward has instructed Eddie Jones to keep his thoughts to himself after a row which ensued over the latter, who was filmed calling Ireland 'scum' and Wales a 's*** little country' in a public speech last year.
While the Australian has apologised for his remarks and escaped censure by Six Nations officials, Jones could yet face action by Rugby Union's governing body, World Rugby.
His comments have also caused an unnecessary distraction for his players as they build up to their clash against Ireland at Twickenham on Saturday.
A loss for England could see them finish in an embarrassing 5th place and would be the first time they've lost three games in a row since 2014.
And 2003 World Cup-winning coach Sir Clive Woodward advises Jones to keep a low-profile.
"All coaches go through periods when everything they touch turns to dust — bad selections, clumsy comments, poor decisions — and Eddie Jones is experiencing that in spades right now,'' Woodward wrote in the Daily Mail.
"Eddie and England are under severe pressure. Should he stay as coach? Absolutely.
"Should he get his head down, be much less high-profile and cut out some of the distracting nonsense around the squad? Absolutely.
"There have been several serious gaffes, culminating in the release of a video with some ill-judged and frankly pathetic comments about the Welsh and Irish, just when he and the team did not need it."
England went into the tournament as favourites, but two ultimately toothless and ill-disciplined performances in Scotland and France have seen Jones' side relinquish their Six Nations crown.
And things have only gone from bad to worse, with Jones embroiled in controversy regarding his off-field behaviour.
''It would be interesting to see how he would have handled this had it been a player making these crazy comments. They were never going to sound good. Eddie knows this,'' Woodward added.
"Make no mistake, this is a major distraction ahead of a must-win game and I can only imagine what the team room is like with these headlines swirling about. Compare it with the Irish team room — it is chalk and cheese.
"The worrying thing is that we have seen a pattern emerging over the last month or so with the coach getting things wrong off the field and behind the scenes.
"It can undermine the authority he has with the team. Getting distracted is suicidal for any international rugby team, let alone the coach aiming to be the best."
It's been a strange season for Jones, having made personal comments about Welsh pair Rhys Patchell and Alun Wyn Jones and then staunchly defending Mike Brown, before dropping him from the squad to face France,
But England need Jones' mind focused solely on preventing Ireland achieving the Grand Slam and his side from a truly disastrous end to the season,
