Pat Fenlon says that Ireland's lack of quality all over the park is a concern after they once again failed to win on Sunday.
The scoreless draw with Wales at the Aviva means that Stephen Kenny's record reads four games, no wins, three draws, and one defeat, with Shane Duffy's late goal in Bulgaria the only time the team has found the net.
The Republic's last victory came in a friendly against New Zealand in November of 2019.
Qualification for Euro 2020 ended on Thursday with a defeat on penalties to Slovakia, while a trip to face Finland on Wednesday is significant in that another failure to pick up three points would leave Ireland staring Nations League relegation in the face.
Speaking on RTÉ Radio 1's Sunday Sport the Linfield General Manager says Kenny has plenty of work to do before the start of the World Cup qualifiers next spring.
"There's a certain lack of quality at the top end of the pitch," Fenlon began.
"Possession of the ball was good again (against Wales). I've watched so much international football. Teams drop off and let you have the ball.
"It's when you get into them areas where you can hurt team and unfortunately we just don't have that real quality at the moment.
"And then in that centre-forward position we don't have an out-and-out goalscorer.
"We saw over a long period of time Robbie Keane win games for us - not on his own - but one or two chances that we create in games and you knew he was going to take.
"We just don't have that at the moment."
Ireland had 46% of the possession on Lansdowne Road, with Shane Long heading the host's best chance of the game over the bar shortly after the restart.
But for Fenlon, the problems aren't just up front.
"The midfield is a concern," he continued. "We've got five or six central midfielders who are all very, very similar; good hard-working midfielders, get about the pitch, move the ball ok.
"But none of them have that killer pass that can open the door."
Speaking about the shape that Kenny is trying to put on the team, Fenlon questioned the wisdom of retaining Jeff Hendrick as a number 10.
"If you're going to play a player in the 10 for me, he's someone whose got real guile, that can see a pass, can slip balls down the side for players coming in off the line, or centre-forwards.
"Or you've got one there that's going to get beyond the striker, and I don't think Jeff does either of them for me.
"With his back to the goal he's not good enough to play in that 10 role. So it's a dilemma for the manager at the moment."
"He (Kenny) has got to be careful as well. Everybody wants to pass the ball, and play great, sexy football.
"But you have to have the players to do that. So you've got to find a system that suits the players that you have.
There are strengths in the team, with the former Shelbourne manager confident that the side won't concede too many goals.
"We've a very good goal-keeper, he pointed out. "At the back we look solid enough.
"But from there up it's about winning football matches and we haven't managed to do that.
"There's a good bit of work to be done, and you've got the be fair to the manager as well. It's the start of a long process."
