The 54-year-old, who took Ajax through to the Europa League final against Manchester United in 2017, has signed a contract to 30 June 2020. Bosz will be joined at Leverkusen by his assistant coach Hendrik 'Hendrie' Krüzen.
"Heiko Herrlich gave our team an important boost last year after a very difficult season and he took us into Europe. We were convinced and determined to turn the corner with him as head coach. Unfortunately, there has been an undeniable stagnation in the development of the team. Even though we are within reach of the European positions at the end of the year we find ourselves in a situation after a less than satisfactory first half of the season that makes a change of coach essential from our point of view," said Rudi Völler as sporting managing director in explaining the decision.
"With Peter Bosz as manager we want to get back to meeting our ambitious targets as quickly as possible," declared the Bayer 04 chairman Fernando Carro. "Of course, that is also down to the players. They have to consistently show their undoubted ability, which unfortunately has rarely been evident over the past six months."
In the view of Bayer 04 sporting director Simon Rolfes, Peter Bosz wants to play "Attacking, high tempo and exciting football. He has always demonstrated particular passion in working with young players wherever he has coached. Therefore, Peter is an excellent fit here with us as we have placed great emphasis on developing highly talented youth players and bringing them through to the top level in a balanced combination with experienced pros for many years. Our team will benefit from having Peter Bosz as our coach," declared Rolfes. "Particularly at Ajax, he demonstrated he can improve young players, build teams and also compete on the European stage."

Under Carles Martínez, the Werkself have so far proved unbeatable at the BayArena. The Spaniard has led his team to victory in all three of their most recent home matches – and, it's worth noting, without conceding a single goal. On Sunday, 18 October (kick-off: 15:30 CEST / live on DAZN and Werkself Radio), current league leaders SC Freiburg will make the trip to Leverkusen, but will be without their top scorer. What's more, the Werkself have won all three of their previous home matches against the Black Forest club. With a goal, Patrik Schick could not only secure a fourth consecutive victory but also set a memorable record. Meanwhile, on what will be the ‘Health Day' at the BayArena, much of the focus will be on physical wellbeing. Today's matchday news.
