I can't get pics , but I'll try and describe some of the changes for you (going from memory here!)
You can get the pics, but you have to visit each club's site.
Ok here goes;
DC United Home : Seen the new France home kit? Imagine it's black and the red bar across the chest is split into three white stripes (Like DC's shirt last year) For PES3, I'd use the template that has the adidas stripes on the sleeves, with a horizontal bar across the chest. Both the bar and sleeve stripes are white. Shorts are black with the white adidas stripes, and the socks are black too.
DC Utd Away: No change from last year - Very similar to AC Milan's away shirt, except the stripes are red. Doing as above (except white instead of black - and red stripes and bar) will get you a pretty good result.
NY/NJ Metrostars Home:
Remember Inter Milan's home kit last season? Just replace blue for red (leave the black and gold in place) and there ya go! Shorts are black, with gold trim as are the socks.
Chicago Fire: See the template that has a black bar across the middle with red trim and red stripes down the sleeve? Make the main colour red, and the others white and you get the general look of the kit, shorts and socks are also red. The away one is reversed - white with red bar as are the shorts and socks.
Sorry it ain't much, but I hope it helps.
Mike.
