Will Still is expected to be announced on Sunday as Southampton's new manager.
The 32-year-old Englishman revealed last weekend he was leaving French club Lens to return to the UK.
Multiple sources have told BBC Sport that Still is set to be in the stands at St Mary's for bottom club Southampton's final Premier League game of the season against Arsenal on Sunday.
He is expected to sign a three-year contract with the Saints, who will return to the Championship next season after their relegation.
Still's appointment has been complicated by negotiations around making his brothers, Nicolas and Edward, part of his backroom staff and releasing him from his contract at Ligue 1 Lens, which runs until 2027.
