Tax loophole that lets them declare a proportion of their wages as a payment for their "image rights" taxed at 20% instead of their wages being for the actual work they do like the rest of us have to pay.
Other than the Queen, Premier League footballers are the last people who should be talking about giving an "extra" 1%. This is a group who upscale their mansions and cars by reducing the amount they have to pay to schools, hospitals, welfare and the infrastructure we depend on to generate wealth.
Mata is having an existential crisis which is very common among all people of a good nature regardless of their wealth. I just challenge the notion that 1% is somehow an acceptable answer to that crisis from the position footballers are in.
