Adkins is understood to have attended several City matches this term, including the recent draw at home to Ipswich Town.
Hull City have appointed Nigel Adkins as their new manager on an 18-month contract.
The duo will take first-team training this morning, as they prepare Hull for Saturday's clash with Brentford at the KCOM Stadium.
Slutsky left the Championship club by mutual consent on Monday, just six months after replacing Marco Silva at the KCOM Stadium.
The former Southampton manager Adkins replaces the Russian Leonid Slutsky, who was sacked last Sunday with Hull recording just four wins in 20 games to sit three points above the relegation zone in 20th position.
The club made the announcement via its official website on Thursday morning in a brief statement detailing Adkins' arrival.
The 52-year-old has agreed a contract with Hull until the end of next season and takes assistant Andy Crosby with him.
Adkins led Southampton to the Premier League in 2012 and has also managed Scunthorpe United, Reading and Sheffield United.
Adkins began his managerial career at Welsh club Bangor City before moving to Scunthorpe United in 2006, where he twice guided the club to promotion from League One to the Championship during his four years at Glanford Park.
