Xabi Alonso has replaced Gerardo Seoane as Bayer Leverkusen's head coach.

Former Liverpool, Real Madrid and Bayern Munich midfielder Alonso coached Real Sociedad B between June 2019 and May 2022, having previously worked in Los Blancos's youth system.

The 40-year-old has now been handed his first head coach role at the top level on a two-year deal, with Leverkusen opting to part ways with Seaone after a dismal start to the season has left them sitting 17th in the Bundesliga.

"Gerardo Seoane has done a good job for Bayer 04 over the past year and a half, above all by qualifying for the Champions League," said sporting director Simon Rolfes. 

"Unfortunately, we have strayed from the road to success. From our point of view, the early elimination from the DFB-Pokal, but especially the fact that the current position in the Bundesliga is far below our expectations, made the change of coach imperative.

"In Xabi Alonso, we have signed a coach who, as a player, was an absolute world-class professional for many years, an intelligent strategist and extremely successful in three of the most demanding European leagues."

Alonso, who helped Spain win the 2010 World Cup, made 79 Bundesliga appearances for Bayern between 2014 and his 2017 retirement, winning three successive league titles under Pep Guardiola and Carlo Ancelotti.

"I know Leverkusen from my time in Germany as an excellent club," Alonso told his new team's official website. 

"Bayer 04 have always had great players, and I see a lot of quality in the current squad too.

"During discussions with the club, it quickly became clear that, despite the current difficult situation, ambitious goals are still being pursued in principle. I am very excited about this task and I am sure that we will live up to this claim."

Seaone's final game in charge was a 2-0 Champions League loss at Porto on Tuesday, Leverkusen's fourth defeat in their last five away games in the competition. 

Bayer Leverkusen have confirmed the signing of Mitchel Bakker from Paris Saint-Germain for a reported €10m fee as the Bundesliga side look to bolster their defence.

Bakker, 21, makes the move to Leverkusen on a four-year contract and links up with new coach Gerardo Seoane.

Originally coming through Ajax’s highly acclaimed academy, the left-back made just two senior appearances before moving to France on a free transfer as PSG secured his services with a four-year deal.

In his debut season for PSG in 2019-20, Bakker won a domestic treble, playing the entire match in both the Coupe de France and Coupe de la Ligue finals against Saint-Etienne and Lyon respectively.

The Netherlands Under-21 international typifies the modern-day wing-back, frequently providing as much in attack down the left flank as he does in a defensive sense.

Bakker made 26 Ligue 1 appearances last term and supplied two assists, although these numbers do not tell the full story of his influence.

Leverkusen's new signing (16) created more chances from open play than any other PSG defender, while he also made the most recoveries (124) of the full-back options in the squad.
