Gary Speed is focused on rebuilding after seeing Wales suffer defeat to Republic of Ireland in his first game in charge.
The Welsh were comprehensively beaten 3-0 at the Aviva Stadium in Dublin in the opening game of the Carling Nations Cup on Tuesday night.
But Speed insists some positives can be taken from Wales' display and says they will work on their weaknesses.
"It's disappointing, obviously," Speed told Sky Sports News.
"There's things in there we can look at and improve, and there's things we can take heart from.
"If we look to the game it's pretty easy to work out where we went wrong and how to fix it."
Captain James Collins rued several costly errors made by Wales during the clash, admitting some of his side's old failings had reared their heads.
"We went in at half-time quite happy as they had not created that many chances," said the Aston Villa defender.
"But we made individual errors which cost us and that has been the case in the past, and we need to cut those out if we are to move on.
"But this is the start of a long campaign under the new manager."
