Chris Coleman's contract as Wales manager is set to be extended beyond the 2016 European Championship finals.
Coleman is expected to be rewarded with a two-year extension until after the 2018 World Cup for guiding Wales to a first finals since the 1958 World Cup.
The Football Association of Wales are expected to announce the 45-year-old's improved contract on Monday.
Coleman, whose current deal ends after Euro 2016, became Wales boss in January 2012, replacing the late Gary Speed.
The FAW have called a news conference with Coleman, chief executive Jonathan Ford and president David Griffiths for Monday in Cardiff.
Coleman, the former 32-cap Wales defender, has lost just one of his last 11 qualifiers and won 12 of his 29 matches in all competitions in charge.
FAW chief Ford had previously admitted: "We very much hope to see Chris leading our team for the World Cup campaign."
Wales begin their Euro 2016 finals campaign against Slovakia on Saturday, 11 June before facing England in Lens and Russia in Toulouse in Pool B.
Wales have not won in their three friendly matches since qualifying for the Euro 2016 finals and face Sweden in Stockholm on Sunday, June 5 before their Championship opener in Bordeaux.
Former Wales managers Terry Yorath and Mark Hughes had urged the FAW to secure Coleman's future before Euro 2016 while most-capped current international Chris Gunter insisted the players wanted the former Fulham and Coventry boss to continue.
The Welsh team start their 2018 World Cup qualifying campaign in September when they host Moldova in Cardiff.
