Wales manager Chris Coleman says victory over Macedonia was his most enjoyable - but has changed nothing regarding his future in the job.
Wales were missing 11 players from Coleman's initial squad selection - but managed to secure a first win in five games, thanks to Simon Church's goal.
Captain Aaron Ramsey missed a late penalty at the Cardiff City Stadium.
"I enjoyed the win tonight more than any other because there has been a lot said and we were up against it", Coleman said.
"Had we lost this game, I would have been out the door, no doubt."
"The contract will be talked about but nothing has changed. I am not sure what anyone can do if we haven't got our best players all the time. It would make no difference what manager is sitting here in front of you."
"We now face a huge test on Tuesday against one of the best teams on the planet in Belgium and I am not looking beyond that."
Defender James Collins is set to go straight into the Wales team to face Macedonia, after meeting Chris Coleman earlier this week to resolve a dispute over whether Collins rejected a call to go on stand-by for the squad last month.
With Wales suffering from an injury crisis, Collins was called into this squad, and trained with his teammates on Wednesday.
16-year-old Liverpool midfielder Harry Wilson was also included.
10 players from the 23-man squad originally named by Coleman have pulled out through injury.
Gareth Bale, Joe Allen, Joe Ledley, Andrew Crofts, Adam Matthews, Ben Davies, Danny Gabbidon, Sam Ricketts, Jack Collison and captain Ashley Williams are all missing.
The tournament in Brazil next summer is yet another which Wales have missed out on, after just two wins from eight qualification games.
Macedonia can't qualify for the World Cup either, but both sides can still leapfrog Scotland and perhaps Serbia, to finish higher in the group.
FAW chief executive Jonathan Ford previously suggested the results against Macedonia and Belgium on Tuesday, at the end of a difficult qualifying campaign, will be taken into consideration before anything is finalised.
