It seems he's picked bits from moments of his life; him as a kid, continent of Africa for his African roots, Germany outline for his German roots etc.
Don't know what the clock means or the numbers below it?
He's covered the badge that people were saying was City's which makes sense for himself and his future, he's obviously going nowhere but rules out him being insane (although that tattoo is fucking massive and a bit mental).
I know he had that nasal surgery but this could also be why he got a bit of extra time off, maybe needed time to recover.
