Professional soccer can be a lucrative career: The second and third highest-paid athletes in the world are soccer players. And, when young players land their first big paycheck, they tend to splurge on the same thing, Spanish star Hector Bellerin tells online investing service Wealthsimple: "In football, we have this thing that we all carry to training — our wash bag — and all the players come in with Gucci or Louis Vuitton. And so, with your first big paycheck, that's what everyone would go and buy."

"As footballers we'd get paid on the 28th of every month," he adds, so, "by the first of the month, every young player had a new wash bag."
