Michael Flynn hailed a "professional" display from Newport County AFC as they progressed through to the Emirates FA Cup third round with a 3-0 victory over Salford City.
Jamie Proctor, Padraig Amond and Saikou Janneh all netted in the second half to round off a convincing performance against the Ammies, who were reduced to 10 men when Brandon Asante was shown a red card for a challenge on Tom King.
But Flynn felt County should have added to their tally against the Ammies, and says he wants his players to be more clinical in front of goal.
"We were excellent," said Flynn.
"We didn’t take our foot off the gas, they kept being professional and it was a very good performance.
"I thought we were by far the better team and it should have been 7-0 really. They didn’t have a shot on target even when they had 11 men.
"I keep saying it and we’ve scored three, but it should have been seven. We missed a penalty and we missed two or three on the line.
"It’s frustrating but it was a great performance second half.”
Proctor, who joined the Exiles on loan from Rotherham United in the summer window, has had to bide his time for his first County goal, but nodded home 11 minutes after the half-time interval to open his account for the season.
"He’s been a little bit frustrated - one or two things haven’t come off for him," Flynn added.
"But it was a fantastic header and he just cushioned it back across from where it came from. It was a good ball from Robbie [Willmott] and it really set us on our way.”
County will be in the hat for the third round draw for the fourth successive season on Monday, but their focus will now be back on their Sky Bet League Two campaign.
The Exiles have a three-point advantage at the top of the league with a game in hand over second-placed Cheltenham Town, and travel to the Robins' Gloucestershire rivals on Tuesday evening.
"We’ve got Forest Green away now - it’s going to be a tough one.
"They have started well as well. They are always there or there abouts in the top half so it’s going to be a difficult game, but we’ll give it our best shot.
"There won’t be a let up, I’ve got a great bunch of players and they’ve shown that we've got a good squad as well.”
