The Canaries' boss was left frustrated following the 1-0 defeat at the DW Stadium on Saturday which has opened up the battle to avoid relegation as third-bottom Aston Villa are now just four points behind his side who sit in 14th position.
Hughton, who has already agreed a deal to sign Sporting Lisbon's Dutch hitman Ricky van Wolfswinkel in the summer, felt Norwich should not have lost to the Latics. And he appears intent on strengthening his forward line with players who are 'clinical' enough to make a difference in tight matches.
Hughton, whose side have won only once in the last 14 outings, said: "It's about clinical moments, and they had the one in the game that got them the goal.
"I thought we were good in that first-half period - we broke well, and probably away from home, that's as much as we've got into the final third.
"It's two things when you're away from home though - if it's a close game you've got to make sure you keep that clean sheet, or you've got to have that little bit of quality that gets you that goal.
"We didn't have that today - it's something that we were guilty of and something we'll have to look at but it was a never a game that I felt we were going to lose."
