If you’re a football fan, then chances are you own a football shirt of some sort.

When you were younger, you probably received the home strip of your favourite team every year with the name of your favourite player on the back of it.

But what have you done with those shirts since?

They might be at the back of your wardrobe or you may have got rid of them at a car boot sale.

But if you do still have them somewhere in your house, you may want to fetch them.

The brilliant Casumo website has revealed the 10 most valuable football shirts of all-time - and you might just own one of them.

What makes a shirt valuable, we hear you ask. Well, Casumo say it’s a mix of three things: What happened on the pitch, the design and the availability.

If you do own one of these 10, you should probably cash in!
