Asher Opoku-Fordjour of Sale Sharks, the England loosehead prop, then surged through a swathe of green shirts for a fantastic solo try but James McNabney’s close-range effort would end the first half.
England rallied again, with Rekeiti Ma’asi-White going close after a cute pass from Joseph Woodward, his centre partner. Mangan was sin-binned for a breakdown offence on the back of that run and a powerful scrum earned England a penalty try.
Minutes later, Woodward, the Leicester Tigers inside centre, scythed Ireland from his own 22 and exchanged passes with Slevin to continue the move. England recycled and Jacob Cusick finished out wide.
From 24-15 behind, Ireland would soon be 34-24 in front. First Fintan Gunne, the Leinster scrum-half, sent Ruadhán Quinn over the whitewash with a beautiful kick-pass. Prendergast whose misses from the tee proved costly then released full-back Henry McErlean for Ireland’s fourth try and centre Hugh Cooney sliced through for number five.
