Wales midfielder David Vaughan hopes Brian Flynn will be appointed manager on a permanent basis, regardless of the result against Switzerland.
Flynn was named caretaker boss following John Toshack's departure but his first game in charge ended in defeat against Bulgaria on Friday.
The situation will be reviewed after the next Euro 2012 qualifier on Tuesday, meaning that victory in Basel would boost his chances of being retained.
Vaughan believes Flynn deserves the opportunity even if Wales lose again, claiming he is the man to take the team to the next level.
And the Blackpool player has urged his international team-mates to produce an improved performance, saying: "We have just got to pick ourselves up for Tuesday.
"We have only had a few days' training with him [Flynn] but if he is around long term I think you will see the benefits in the performances.
"No-one wants to let him down and hopefully he will get the job, regardless of the results, if we play well. Hopefully we can do the job for him.
"It is going to be very difficult to qualify but we have just got to try to win every game and we will see where we go."
Wales have failed to collect a point from their opening two Group G fixtures but Vaughan feels they were unlucky to come away with nothing from the clash with Bulgaria.
"We were disappointed to lose the game," said the 27-year-old.
"I thought we created enough chances to at least get a point. The performance was a lot better than it has been over the last few matches.
"Hopefully we can just keep going and produce a good performance on Tuesday.
"Brian urged us to get on the ball and play from midfield and just be a bit more attacking.
"The goal took the wind out of our sails a bit, but it was a good finish and these things happen at this level.
"We have just got to be positive. A lot of people would like to be in our position, so we have got to appreciate it and try to do the best we can."
