Blackpool midfielder David Vaughan believes Wales would have a bright future under Brian Flynn - if the players can secure the manager's job for him this week.
Wales face Switzerland in Basle on Tuesday in the second and final match of Flynn's spell as caretaker boss, needing to win to retain any realistic hope of qualifying for Euro 2012.
Flynn was put in charge for this month's double-header against Bulgaria and the Swiss, and after defeat in the first of those matches on Friday he now has just one remaining chance - on his 55th birthday - to impress.
Wales have no points after two games in Group G and another loss would all-but end their campaign just a month after it began.
Vaughan said: "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."
