AC Milan are preparing for a strong match in Germany in a difficult environment in front of the 'Yellow Wall'.
According to what is reported by the Italian journalist, Antonio Vitiello, the Rossoneri team of Stefano Pioli held training with the audio of Borussia Dortmund fans chanting.
This is definitely an important decision taken by the coaching staff who want the team to be used to the intense level of noise and have at least an idea about what may be in store for them tomorrow.
