While Chen Zhong was chatting with Alonso, he also took Alonso's coaching manual in hand, and the two discussed recent glories and declines.
"Does it take 30 years to become a great coach?"
"Aren't you not even 60 this year?" Chen Zhong looked at what was written on the cover page of Alonso's coaching manual, and after hearing Chen Zhong's question, Alonso replied: "Am I not a great coach yet?"
When Alonso retired in 2014, he chose to join Real Sociedad B team as an assistant coach, getting up at 4 AM every day to study heat maps of young players' movements.
Three years later, when he moved to Bayer Leverkusen, he requested the medical team to scan players' knee joint pressure data after each training session. This accumulated knowledge eventually transformed into a unique "dynamic load management" system.
