The Football Association of Wales could make a decision on the future manager of the national team at a meeting on Monday.
Assistant boss Raymond Verheijen hopes the leadership will be handed to himself and Osian Roberts.
Wales were left without a manager following the death of Gary Speed in November and Verheijen has revealed a decision could be made at the beginning of next week.
"Tomorrow FAW meet about future of Wales," the Dutchman said on social networking site Twitter.
"Hopefully the board will respect Gary's wish so Osian Roberts and myself can lead the team to Brazil.
"[There is] no need for new manager with new ideas. Our success was based on Gary's clear structure. Everybody knows what to do for mission Brazil 2014."
Verheijen, who has helped coach Holland, Russia and South Korea's national sides, was brought into the Wales set-up when Speed was appointed in 2010.
The 40-year-old helped Speed to organise and inspire Wales to win four of their last five internationals.
