Derek McInnes has agreed a deal in principle to become the new Rangers boss.
Final details are being ironed out but McInnes will leave Hearts, who he guided to a second-place finish in the Scottish Premiership last season, and sign a three-year deal at Ibrox.
McInnes is set to replace Danny Röhl, who has agreed a deal to join RB Salzburg. Rangers will receive around £2m in compensation.
The club's chairman Andrew Cavenagh and CEO Jim Gillespie have moved swiftly while in the US to replace Röhl. McInnes is the only candidate they spoke to formally.
The 54-year-old, a former Rangers player, previously knocked back the chance to manage the club in 2017. He was pipped to the league title by Celtic on the final day of the campaign in his first season at Tynecastle.
Salzburg want to appoint Röhl as Daniel Beichler's replacement in Austria. Your Site News previously reported that any possible deal would need to meet Rangers' terms, as Röhl has two years left on his contract at Ibrox, having joined the club last October.
Röhl took over from Russell Martin, with the team sixth in the league and led them into the title race before falling short towards the end of last season.
Cavanagh and Gillespie are in Boston and watched Scotland against Haiti at the World Cup. Hearts chief executive Andrew McKinlay was also at the match as part of a Scottish FA delegation in his role as Scottish FA vice-president and so too was McInnes after his close-season holiday in America.
Rangers return for pre-season training next week.
Rangers have already begun a club-led summer rebuild with the likes of Gillespie, executive director Fraser Thornton, technical director Dan Purdy and consultant Stig Inge Bjornebye working with the coaching team to add to the squad.
Scotland international Lawrence Shankland was the first confirmed signing, joining from Hearts on a two-year deal with the option of a further 12 months.
He moved from Tynecastle to Ibrox upon the activation of a clause in his deal that saw him move for free, having scored 20 goals in all competitions last season.
