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, in the same group as England, face Switzerland in Basle tomorrow 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 tomorrow.
“We have only had a few days' training with Brian 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.”
Flynn, who has impressed in charge of Wales Under-21s, was asked to oversee the senior side when John Toshack stepped aside after defeat in Montenegro last month.
Vaughan believes Flynn has already made a difference, even though the team could not avoid a 1-0 loss to Bulgaria at the Cardiff City Stadium.
The 27-year-old Blackpool player said: “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.”
Wales travelled to Basle with a 22-man squad considerably different from the initial 24-man group named by Flynn for the two games.
Neal Eardley, Danny Gabbidon, Robert Earnshaw and Brian Stock all failed to report and Joe Allen and Ched Evans then pulled out after initial training.
All were for injury reasons except for West Ham defender Gabbidon, who retired from international football. Darcy Blake, Adam Matthews, Neil Taylor, Andrew Crofts and Ryan Doble joined the group.
Further changes were made yesterday after Joe Ledley was given leave to return home and join his partner, who is expecting their first child.
Hal Robson-Kanu was forced to withdraw with a hamstring injury while defenders Chris Gunter and Sam Ricketts are now suspended for the Switzerland game.
Bournemouth defender Rhoys Wiggins, Swansea midfielder Jazz Richards and Yeovil's on-loan Swans player Shaun MacDonald were added.
Stand-in captain Ashley Williams is a slight concern with a foot injury.
