The 21-time Grand Slam winner, who has career earnings of £133.7m ($159m) – the most of any male tennis player in history – says he should not be made to feel guilty about his wealth after growing up in an underprivileged household.
“I’ve been very fortunate in my life, and I’ve been blessed to have that income as a result of my tennis and the success I’ve had with my family and team,” he added.
“Every euro I earned was created through hard work, sweat and tears and I don’t take anything ‘for granted’ because I know very well what it means and what it looks like to have nothing on the table, among five family members, during war and sanctions.
“Let’s not forget where I come from and in which times I grew up. Actually, I know the other side of reality very well.”
