Imagine the likes of west bromwich albion and wolverhampton wanderers, it would go right round the back and on to the front.
Have you seen the length of German team's names? West Brom and Wolves have nothing on them
They just use their nickname or city name on the back of the shirts, cos yes, if they used the full team name, there would be no room for anything else!
Couple example:
FSV Mainz 05's full name is 1. Fußball- und Sportverein Mainz 05 e. V.
They just have 'Mainz 05' on the back of their shirts.
Borussia Dortmund's full name is Ballspielverein Borussia 09 e.V. Dortmund
They just have 'Dortmund' on theirs.
