Rodgers reportedly asked Balotelli to take his position during a drill at Melwood in which the Italian was expected to help defend a corner.
And the former Manchester City forward is said to have replied with a simple: “No."
When Rodgers asked him to explain his response, Balotelli continued: “I don't come back for corners. I'm a striker."
Players and staff who witnessed the incident are said to have been stunned by the exchange, which apparently set the tone for his entire Liverpool career.
