DANNY McNamara played right-back and helped Newport County to a fourth consecutive clean sheet in League Two as they defeated Crewe 1-0 on Saturday.
McNamara, 20, has yet to experience defeat in his loan spell as Padriag Amond scored in injury-time to send Newport into fifth.
Newport haven't conceded a league goal since the 49th minute of the opening day against Mansfield.
Flynn said: "I'm not going to dress it up. We were really poor going forward, but as a team we defended well, limited their chances – I don't think they had one clear-cut chance.
"And they've gone for the win and it's cost them."
