The Sporting CP 1999/00 home shirt, made by Reebok, sits right at the turn of the millennium and captures a club utterly confident in its identity. The green and white vertical stripes need no introduction: they are the Leões in their purest form, worn at Alvalade through some genuinely exciting league campaigns. For collectors, this jersey also marks one of the final chapters of Reebok's relationship with the club, making it a quiet but meaningful piece of Portuguese football shirt history.
