German football can be a role model in several ways, Klein said in a recent Xinhua interview.
The 23-year-old, who has previously been linked to interest from Spanish giants, Real Madrid and FC Barcelona, has agreed a contract until June 2025. He will travel to Manchester to join his new teammates after the Netherlands' UEFA Nations League game against Italy on September 7.
During his career as a shuttler, he became a gold medalist in men's singles at the Atlanta 1996 Olympic Games. He also won two All-England Open Badminton Championships in 1995 and 1996, and the European Badminton Championships in 1992, 1994 and 1996.
Germany started brightly on home soil and created the first chance of the game as Toni Kroos' cross into the box allowed Thilo Kehrer to test Spain goalkeeper David de Gea in the 11th minute.
The reasons seem apparent in Klein's view.
Bale added that despite apparently not being in Zidane's plans, Madrid had stopped him moving last season.
The competition in Lausanne's Place de l'Europe played host to a fascinating duel between Duplantis and two-time world champion Sam Kendricks from the United States, whose best jump was 6.02 meters.
In the 65th minute, Dalian's Ke Zhao added a goal of his own and sealed the 4-0 victory.
"I was really focused each game and each point. Especially against top players, one point can make the difference. So I had to stay very calm and keep going," the world number 50 added.
The announcement was made Thursday at the IFA, Internationale Funkausstellung, the world's leading trade show for consumer electronics and home appliances, in Berlin.
"My team was fantastic during the whole race. Today I felt very good, my legs were really good, until the attack I could ride easily. Also, I was very motivated. Many people supported me along the roads, and I want to thank everyone," Valter said after the race.
