Ireland had to come from behind against England to get their bid for a third successive Six Nations title off to a winning 27-22 bonus-point start thanks to a ferocious second half after the visitors had made life very uncomfortable.
England got their gameplan spot on in the first half to lead 10-5 at the break, taking a deserved early lead through a debut Cadan Murley try before frustrating a stop-start Ireland at the breakdown with only Jamison Gibson-Park able to break through.
