The shirt worn by Smith is then auctioned and the proceeds are donated to charity. However Smith has now changed his main shirt for the upcoming season to feature the coloured puzzle pieces, part of the logo of the foundation.

''Michael's nephew has autism and we were thinking for a while how we could support Autism Awareness'', his Facebook fanpage said before. ''It's a fantastic charity, which is close to our heart. After every first round we will auction the shirt and donate the money to the charity.''
