Would you say I am British here?

I was born and raised in London to Nigerian parents (was in Nigeria at age 2-4/2-5)

I spent the latter of my formative years in Nigeria from age 13-21

I then came back to London (England) at age 21

I self identify as each of these 4 : British/English/Nigerian and a Londoner.

In football my club is Chelsea and for the Nationals it’s England/Nigeria
