Wales assistant manager Raymond Verheijen hopes the leadership of the national side will be decided on Monday by the Football Association of Wales.
Wales were left without a manager after Gary Speed's death last month.
"Tomorrow FAW meet about future of Wales," the Dutchman wrote on Twitter on Sunday night.
"Hopefully the board will respect Gary's wish so [fellow assistant] Osian Roberts and I can lead the team to Brazil."
Dutchman Verheijen added: "There is no need for a 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 Netherlands, 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.
He said early last month, before Speed's death, that his contract was due to expire at the end of 2011 and he was evaluating his future.
Wales will begin their World Cup campaign at home to Belgium on 7 September 2012.
