0910 Champs patch - used by champions of the previous season i.e. 0809 Man Utd.

1011 Champs patch - used by champions of 0910 season i.e. Chelsea.

FYI 1011 Champs patches are not out yet in KL so maybe you can wait until 1011 season starts proper to purchase the patches.

You can either buy from Al-Ikhsan BB Plaza and have them applied for you, or buy from chcher and apply them yourself.  Check out the simple DIY section on 1st page, can use home iron also.

officicially you are wrong, ie officially the terms used by aw13 are the terms used by suppliers etc. 10/11 champs patch refers to the patch worn by the champs in season 1011 ie chelsea

but most ppl would refer to them as you mentioned, since they see the numbers printed on the badge itself, ie "0910 champions" for chelsea would be taken to mean "0910 champs patch", which is not what official suppliers call them.

whichever it is just double confirm before buying

That is the player issue version, that is Techfit, the other player issue version is Formotion, the box set that you can buy at Adidas store for about RM500 is Techfit version
