Lynn is likely to make changes for what is – just as last year’s final game against Italy – a must-win match on Sunday.
Wales were brushed aside by a rampant Ireland who made twice the number of carries, metres and linebreaks despite a shocking 25 handling errors which could have inflicted far more damage than the 40-14 scoreline suggests.
“I was disappointed, full-stop,” added Lynn. “The performance against Ireland was not good enough and the players and staff are aware of that.
“We should have been far more competitive but you have to take your chances and you cannot concede 18 penalties against top sides.
“Most of those penalties were down to us and individuals trying to fix problems that weren’t theirs to fix but resulted in putting the team under pressure.
“When we talk about learning from games, that was a massive area for us.”
Wales are awaiting the result of a scan on the hamstring of Harlequins fly-half Kayleigh Powell who was a late withdrawal last week.
However, Lynn was at least relieved that his team were not forced to play two games in five days when the match – rearranged due to the funeral of Pope Francis – was pushed back to Sunday.
