This is the closest I found to the shirts in your icon. Most likely it is a custom design for the team. If it can be purchased it would probably have to come from their sports shop (not the correct term)...like where they sell souvenirs, etc. at the game...if it's like over here in the States.

Most of the time, the real team clothes are not available to the general public...you have to have a team member get it for you.

Don't you just love the feeling of being/getting organized? :)
