Former Manchester United manager Erik ten Hag was appointed head coach of Bayer Leverkusen on Monday.

Ten Hag will replace Real Madrid-bound Xabi Alonso, who led Leverkusen to their first Bundesliga title in 2023-24 and added the German Cup.

Leverkusen were unable to keep up the same pace this season but still finished Bundesliga runners-up to Bayern Munich and qualified for next season's Champions League.

Ten Hag has worked in German football before, spending two years in charge of Bayern Munich's reserve team from 2013.

The 55-year-old Dutchman won the FA Cup and League Cup in his two full seasons at United and led the club to third in the Premier League in 2022-23.

United launched a review last summer and interviewed other candidates after they finished eighth in the Premier League, only to decide to stick with Ten Hag.

But after a poor start to the season, he was sacked on Oct. 28 following a 2-1 defeat at West Ham.

Before United, he helped Ajax to win three Dutch league titles.

Ten Hag has signed a two-year contract.

"With Erik ten Hag, we have brought in an experienced coach with impressive success on the pitch," Leverkusen's sporting managing director, Simon Rolfes, said in a statement, calling his success at Ajax "exceptional."

"With three league titles and two domestic cup wins he and Ajax dominated Dutch football from 2018 to 2022."

"And Erik demonstrated his quality as a coach with the ensuing success at Manchester United under difficult circumstances at times," added Rolfes.

German media reported Leverkusen were also interested Cesc Fabregas, coach of Serie A side Como, but the former Barcelona and Arsenal player elected to stay in Italy.

'An attractive challenge'

Real Madrid announced on Sunday that Alonso will replace Carlo Ancelotti as coach.

Alonso starred as a player for Real. He will take over on June 1 in order to lead the Spanish giants at the Club World Cup.

Alonso worked wonders at Leverkusen, taking the serial underachievers to the Bundesliga title for the first time in their 120-year history despite having never managed at the top level.

Under Alonso, Leverkusen won the league title without losing a match in 2023-24; no club, not even the best Bayern sides or Jurgen Klopp's barnstorming Dortmund, had gone through a league season without defeat.

Ten Hag faces a summer rebuild in Leverkusen, with several Bundesliga-winning stars heading out of the door.

Centre-back Jonathan Tah has already confirmed his exit after 10 years at the club, with Bayern his likely destination.

Midfield maestro Florian Wirtz and winger Jeremie Frimpong also look set to leave, with German and English media reporting that both are headed to Premier League champions Liverpool.

While Tah will leave on a free transfer, Wirtz and Frimpong will command high fees, giving the Dutchman money to work with.

Ten Hag will also seek to rebuild his own reputation, which took a hit during an unhappy time at United.

Calling Leverkusen "one of the best clubs in Germany," Ten Hag said he wanted to "continue the ambition shown in recent years. 

"It's an attractive challenge to set up something together in this period of change and develop an ambitious team."
