Leonid Slutsky wasn't exactly the most successful figure at the MKM Stadium, failing to live up to expectations at Hull City despite having a wealth of managerial experience behind him.
It may have been his first taster of English football when he arrived at the Championship side back in June 2017, coming in to succeed current Fulham boss Marco Silva shortly after their relegation from the Premier League, but he had a decent enough CV.
Not only did he manage CSKA Moscow between 2009 and 2016, but he also managed the Russia national team, managing to secure a draw against England in their opening group game at the 2016 European Championships but being knocked out after suffering a 3-0 defeat against Wales.
Despite having a reasonably busy window in terms of incomings, Slutsky also lost some of his best assets including Harry Maguire and Andy Robertson, both of whom are now competing at the top end of the Premier League.
Still, the results were poor even considering that as the Tigers won just four of their opening 20 league matches under his guidance, also being knocked out of the EFL Cup by League One side Doncaster Rovers.
With this, the Russian left the club in the early stages of December by mutual consent and although it had been a turbulent period for the East Yorkshire outfit, he sent a classy parting message to the club's supporters.
He spent a very brief period out of management before getting back into the game via Dutch side Vitesse in time for the beginning of the 2018/19 campaign, though he was unable to spend a long period at the club as he resigned from his position in November 2019.
Returning to his home nation the following month, he has been at Rubin Kazan ever since, enjoying success last term as he finished above the likes of CSKA Moscow and Dynamo Moscow to secure fourth spot and a place in the UEFA Europa Conference League qualifying phase, but lost out to Rakow this season as they were unable to force their way into the competition's group stage.
President Vladimir Putin's invasion of Ukraine last month has created uncertainty for Slutsky and his side though, although the Russian Premier League is carrying on as normal with Kazan currently sitting five points above the danger zone.
They have no European place to play for this season though with UEFA and FIFA suspending all Russian sides from participating in their competitions - but will want to guarantee their safety with a few more wins on the board.
The fact Filip Uremovic has left for Sheffield United temporarily, as allowed by FIFA regulations, won't help their cause and neither will the fact Silvije Begic has also suspended his contract, though they will be hoping to retain the rest of their squad for now.
