Nick Kyrgios' new tattoo reads 'Give a man a mask and he will become his true self'.
Is it the 'bad boy'? Is it the generous philanthropist? Or is it even the talented tennis player?
After reaching the Wimbledon third round on Thursday with a business-like victory featuring none of his trademark antics, the Australian said he "just wanted to remind everyone" he is "pretty good" at tennis.
He cannot really blame people if they had forgotten.
But this is a player whose natural talent has been ranked among the greats and who, when he is completely focused on his tennis, can beat the very best.
