Robin McBryde said he "felt hurt" by Wales' defeat at the hands of Scotland last month but is confident they will bounce back against Ireland in Cardiff on Friday.
Wales, four-time champions since 2005, have lost two of their opening three matches during the current campaign but have named an unchanged side for the match at the Principality Stadium.
Forwards coach McBryde admits the Wales squad are feeling chastened by their experiences of the 2017 Six Nations Championship so far but has backed to make amends in their final two games of the tournament.
McBryde said: "We hope they (the players) feel a bit galvanised by the fact they get to go again and step up their performance.
"Because there're no changes, there are no excuses. We've shown faith in them as coaches, we feel there's a lot more to come from that group of players, they're deserving of that opportunity and this is their shot at it.
"For myself, personally, there is still a level of hurt there from the Scottish defeat, and I am sure the players are feeling that as well.
"So we need to react in a positive manner against what will be a very confident Ireland team.
"We're in a goldfish bowl and you're aware of it.
"If the national team doesn't succeed you're going to get a fair bit of flak and that's life, nothing changes.
"There's no other way through it other than just rolling up your sleeves and going at it again, maybe a little smarter or learning from your mistakes.
"As far as I am concerned, when you are taking part in international rugby as a player, as a coach, you are under constant pressure. Maybe a little bit more so in Wales."
