The Manchester City midfielder revealed inside oddities like who takes the longest in the shower.
Grealish also gave himself a drenching, by self-naming and shaming for one of the most unwanted individual descriptions.
When morale at the club is at its highest, Grealish disclosed some fun titbits to The Mail.
Erling Haaland is of course clocking up goal records on the pitch, with 51 so far this season.
But now he’s been outed as the City player who clocks up the most minutes in the showers.
And Grealish, so twinkle-toed down the wings at the moment, also confessed his own big weakness.
He rates England pal John Stones as the best dancer but himself the worst.
But the former Aston Villa hero did attempt a high-brow excuse.
Grealish reckons much of his time with music is spent as a “multi-genre DJ”.
Perhaps that’s the disc jockey version of Stones as a footballer – someone who can fill different roles depending on the occasion.
Grealish regards Kyle Walker as the “best dressed” player.
He didn’t say, however, if that was partly because the Three Lions’ right-back has more opportunity to contemplate fashion this term as he’s mainly been on the Etihad bench.
The opposite is true of Rodri, who has been so busy out in the middle as the anchorman but is labelled as the worst-dressed star.
Rodri also got a pasting for his music tastes.
Meanwhile, Grealish had the perfect explanation when asked who was the most laid-back in practice.
Singling out City’s iconic playmaker, he said: “Kev (De Bruyne). But he’s just like, you know, because of how good he is on a match day. He’s just chilled in training.”
