Only want a replica shirt, don't want to have to pay an extortionate amount, and ideally the white jersey.

What size are you looking for?.

I think i need an XL although hard to tell

Would be good to get something byt Wembley as well

Here is a link to a black xl westbrook eqt that is legit but you will not get it in time for wembly they have a green in a xxl aswell.

If youre a member on NFLUK look at the international series 2008 thread , and look at martin3206 thread about the green man pub tailgate party they got guys from germany coming over with merchandise they might have it.

Hmm, not sure if im going to be able to get there any earlier than i already am, hopefully i'll be able to source something through Ebay as i'm in talks with a seller as we speak.

Thanks for your help guys.

If anyone else knows where I can get hold of a jersey in time for Wembley it would be much appreciated.
