Harry Kane reportedly has a special clause in his Bayern Munich contract that could see him earn an extra windfall on top of his wages.
The England captain has enjoyed a stellar start to life in Germany since his £86.4million summer move from Tottenham.
Kane has netted a remarkable 21 goals in just 16 appearances in all competitions, including eight in his past three Bundesliga games.
The 30-year-old has also added seven assists, while his 21 strikes have encompassed three separate hat-tricks.
And, according to German outlet BILD, Kane is set to receive a bonus if he reaches a certain number of goal involvements this season.
