Wales defender Ashley Williams says it is too early to panic after losing their opening 2014 World Cup qualifer 2-0 at home to Belgium on Friday.
Chris Coleman's side must now pick themselves up for Tuesday's tricky trip to play Serbia in Novi Sad.
"We wanted to start off with some points. We haven't," Williams said.
"But that's fine - nobody qualifies in the first game and there's plenty of points to play for and we'll take that into Serbia."
Williams' central defensive partner James Collins was sent off after 26 minutes when the West Ham player caught Belgium full-back Guillaume Gillet late.
But Wales maintain the decision by Swedish referee Stefan Johannesson was harsh as both players were off the ground when they went in for a loose ball in midfield.
The home side also contested the free-kick awarded to Belgium from which Jan Vertonghen scored to seal the win.
"I think we can take a lot of heart from that game, to be honest," Williams added.
"After the last few games we haven't shown what we can do, but [against Belgium] we really gave it a go with 10 men.
"If we'd got a few more decisions and had 11 men on the field it might have been a different outcome.
"Apart from [Collins' sending-off] there were so many decisions that we don't agree with and it was disappointing.
"The way we played, if we show that desire in the next game we can definitely get the win."
Coleman had to send out a patched-up team at Cardiff City Stadium, with Joe Allen withdrawing ill prior to the match to join a casualty list including Craig Bellamy, Neil Taylor, Andrew Crofts, Wayne Hennessey and Jack Collison.
Liverpool midfielder Allen has recovereded from illness and is fit to feature against Serbia in Novi Sad on Tuesday, although Collins will be missing through suspension after his dismissal.
Serbia drew their opening qualifier 0-0 away to Scotland on Saturday.
"We've said from the outset we want to qualify... we want to win games," Williams said.
"International football away from home, sometimes you've got to suck up the pressure.
"The good thing about our team is that we've got players on the break, like Gareth Bale who can score a goal from his own half, he can dribble the ball, carry it all the way through.
"So when we play away we're suited for those type of games."
The result against Belgium left Coleman without a win from his three games in charge and Wales have now lost four games in a row without scoring.
