I'm not, as a general rule, a big fan of Chelsea shirts but this one is worth it's place in the museum based on it's rarity as I haven't noticed Adidas using this design anywhere else. What looks like a plain white shirt at first glance is actually subtly striped with a grey wavy line. It also carries the name and number of Ghanaian midfield powerhouse Michael Essien. Essien was the archetypal modern player and a real all round midfielder until injury took the edge off of him. Although he can occasionally throw in the odd utterly atrocious tackle.
