Leonid Slutsky is to leave CSKA Moscow following Wednesday's Champions League group game against Tottenham Hotspur.
The 45-year-old took over as CSKA head coach in 2009, and has guided the Russian club to three Premier League titles and two domestic cups.
Alongside his role at CSKA, Slutsky also took charge of Russia's national team after Fabio Capello's departure in 2015 but his stay ended after the team's group-stage exit at Euro 2016.
A CSKA statement on Tuesday confirmed Slutsky's impending departure. It read: "After the match with Tottenham in London, Leonid Slutsky will leave his post as head coach of CSKA Moscow.
"CSKA give their thanks to Leonid Slutsky after seven fruitful years together, including three league titles, two Russian Cups and two Russian Super Cups, as well as the incredible emotions that the team under his leadership have given to the huge army of fans.
"Our club doors are always open to you, Leonid!"

Marathon runner Callum Hawkins has become the first British athlete to be selected for next summer's World Championships in London.
The Scot, 24, who finished an impressive ninth at the Rio Olympics in only his third marathon race, has been confirmed by British Athletics as the first member of its team for August's showpiece.
British Athletics performance director Neil Black said: "We are delighted to confirm Callum's selection for London. He has only competed over 26.2 miles three times, but we can already see the talent he has, finishing eighth at the London Marathon in 2016 and following that up in Rio at the Olympics with a brilliant ninth place."
Black added that the British team for the London World Championships would be "large and competitive".
George North will not play for Northampton again until he has been assessed by an independent expert in head injuries.
The Welsh wing, who has suffered a series of concussions, was cleared by Saints medics to continue playing during Saturday's Aviva Premiership clash with Leicester despite replays suggesting he had been knocked out following a tackle from Adam Thompstone.
Questions have been raised about whether the player's welfare was best served by his return to action but Northampton insist they were fully in compliance with World Rugby's head injury assessment protocols.
The club does admit, however, that the footage available to them at the time was limited and have taken the precautionary steps of withdrawing North from action pending the specialist's verdict.
Toby Alderweireld returns to the Tottenham squad for Wednesday's Champions League game at home to CSKA Moscow.

Provisional Spurs squad: Lloris, Vorm, Lopez, Rose, Davies, Vertonghen, Alderweireld, Carter-Vickers, Wimmer, Walker, Trippier, Dier, Wanyama, Winks, Dembele, Eriksen, Alli, Sissoko, Onomah, Nkoudou, Son, Kane.
Sunderland forward Duncan Watmore is set to miss the rest of the season after scans revealed a cruciate ligament injury suffered in Saturday's win over Leicester.
Watmore has visited a specialist in London, and the 22-year-old is facing an extended period on the sidelines.
Sunderland said in a statement: "Sunderland boss David Moyes has confirmed that Duncan Watmore is likely to miss the rest of the Black Cats' season following the results of his scan on Monday.
"Results from the scans revealed Watmore has suffered cruciate knee ligament damage."
Watmore's absence will be a significant blow for manager Moyes who is already without Paddy McNair, Lynden Gooch and Lee Cattermole for the long term.
The former Altrincham youngster had started 11 games for Sunderland this season and proved a major factor in their recent revival.
But Watmore was stretchered off after a clash with Leicester's Christian Fuchs during the win over the Foxes, and the scans have realised Moyes' worst fears.

Bristol have announced the signing of Ireland international lock Dan Tuohy, who will move to the Aviva Premiership with immediate effect, leaving Guinness PRO12 side Ulster.
Bristol-born Tuohy won the last of his 11 Test caps in 2015, while he had spells at Gloucester and Exeter before heading to Ulster.
Tuohy's arrival at Ashton Gate follows the announcement on Monday that current Connacht boss Pat Lam will take over as Bristol head coach next summer.
Bristol are six points adrift at the Premiership basement, and they face a crunch clash against 11th-placed Worcester on Boxing Day following a two-week break for European action.
"We are pleased to welcome Dan into the fold - he is a formidable presence in the second row and an experienced lineout operator," Bristol's acting head coach Mark Tainton told the club's official website.
"I know Dan well from his time in the Ireland international set-up. His knowledge of the game at the highest level, as well as his leadership skills, will be of significant benefit to the team."
Tuohy added: "When speaking to Mark, it was clear to see the vision he had for the club. I am very excited to have the opportunity to add something to the group.
"I want to thank Ulster Rugby and the IRFU (Irish Rugby Football Union) for the past seven-and-a-half years, and wish them the very best in the future. My attention now turns to helping Bristol retain their place in the Premiership."
Mercedes are considering Fernando Alonso as a replacement for retiring world champion Nico Rosberg.
But two-time championship winner Alonso is about to enter the final year of his three-year deal with McLaren, meaning Mercedes may have to look elsewhere.
"You have to consider Fernando," Mercedes boss Toto Wolff told Sky Sports' F1 Special: Nico The Brave show.
"He is a driver I respect a lot. He combines talent, speed and experience. It's all there.
"But he is in a contract with McLaren-Honda at the moment and we just need to weigh all the other options up."
Mercedes face a race against time to bring in a new driver alongside Lewis Hamilton, with pre-season testing due to begin in February.
Rosberg made his surprise announcement last week, just five days after sealing the drivers' championship.
