Eddie Jones has attempted to unsettle Ireland ahead of Saturday's Autumn Nations Cup showdown by placing the spotlight on their scrummaging technique.
England's head coach has aimed a series of psychological jabs at Andy Farrell's men, who he mischievously referenced as the 'United Nations' in allusion to the number of southern hemisphere players in their starting XV.
But the key strike was made against Andrew Porter after Jones sought to bring the attention of French referee Pascal Gauzere to the Leinster prop when the rivals collide at Twickenham.
"Every battle is a tough battle. We were going well and Ireland beat us for a Grand Slam in 2017. We'll never forget that.
"These are good battles between two good rugby countries, different sized countries, different histories, but the battles and traditional rivalry are enormous and it needs to be respected."
England field an unchanged backline following their 40-0 rout of Georgia but there are four changes in personnel to the pack with props Kyle Sinckler and Mako Vunipola and flankers Tom Curry and Sam Underhill restored.
George Ford has recovered from an Achilles injury to secure a place on the bench.
