In world football, the rising sums of money spent on player salaries are gathering more and more scrutiny and criticism.
Public disapproval of outlandish weekly wages for footballers was stoked by the Olympics. Meanwhile, UEFA president Michel Platini is standing firm in his commitment to enforcing financial fair play, a set of guidelines for European clubs to keep spending in line with revenues.
Part of UEFA's aim is to curb transfer inflation to prevent a stockpiling of the world's top players by a handful of well-capitalised clubs.
But financial fair play also targets ballooning player salaries, which now account for an average 70 percent of club revenues in the Premier League—a record high that is unsustainable under the fair play guidelines.
According to Sporting Intelligence, the top four salary outlays across all sports worldwide are in soccer—Barcelona, Real Madrid, Manchester City and Chelsea.
Those teams are liberally stocked with players whose worth is hard to question—the likes of Xavi Hernandez, Lionel Messi, Yaya Touré and Cristiano Ronaldo.
But there are plenty of players around the world of football who just can't seem to justify their contracts.
