Roy Keane was "disappointed" with John Egan's role in Riyad Mahrez's second goal in Sheffield United's 3-0 FA Cup semi-final defeat to Manchester City on Saturday.
The strike came at the end of a great solo run by the Algerian international, but Keane believes his fellow countyman and his defensive partner Jack Robinson could have both done better.
The former Manchester United captain said on ITV: "I would be really disappointed with Robinson and Egan here. Yeah, there's runners - if he plays them in and they score, then no problem. You can't just let him walk through the middle.
