Ryan Giggs insists Wales can fire without Gareth Bale despite this latest blank against 10-man Ireland.
Wales remain top of Nations League Group B4 after a goalless draw against Ireland following a 3-0 friendly loss to England.
Boss Giggs was unimpressed with the lack of creativity from his side against the Irish, who had James McClean sent off late on.
It was the second successive game Wales have failed to score after record scorer Bale opted to work on his fitness at new club Spurs.
Giggs, whose side take on Bulgaria away on Wednesday, said: “Our performances have to be better and they will be.
“We need to create more, we need to get our key players on the ball quicker.
“Once you get to the final third, the decision-making needs to be good with a better first touch on the ball and delivery into the box.
“It is not about personnel, it is about the players on the pitch and we had enough.
“We definitely need to be better in and around the area.

“But it’s three Nations League games, three clean sheets including two away games, so you have to be happy.”
Manchester United winger Daniel James was very quiet in Dublin before being replaced by Bournemouth’s David Brooks late on.
Giggs will be without target man Kieffer Moore in Bulgaria as he is suspended after picking up another booking in Ireland.
He added: “We will look at how Bulgaria play and see what we feel will be best to get that good result.”
Giggs, whose squad were tested on Sunday, said the visitors were happy to fulfil the fixture despite an Irish player testing positive for coronavirus and having to isolate along with four team-mates who were close contacts.
“We realised what had happened with Ireland but had no concerns, we had to concentrate on ourselves and going out to perform,” said Giggs.
