All right, so this book has been contracted and all so I won't be able to use the real names of footballers. I don't know whether I can do this or not but since I can't use actual names, I'll be dropping the real names of footballers whose names I rearranged (I might delete later if research shows that this could be legally troublesome)
I'm doing this off the top of my head because I don't want to re-read the entire book for the fifth time.
In no specific order:
Robert Carlitos: Roberto Carlos
Leornado Massi: Lionel Messi
Christian Ronald: Christiano Ronaldo
John Oblek: Jan Oblak
Romuldinho: Ronaldinho
For the clubs:
Liverpool Red: Liverpool
Manchester Blue: Man City
Catalan FC: Barcelona
Leeds FC: Leeds United
Teesside FC: Middlesbrough
Birmingham City (no change here)
Birmingham United: Aston Villa
(Again, it's off the top of my head. Please comment if I've missed any one)
