Adidas, Nike....same sh*t. Both are equally capable of making bad designs. I don't mind Adidas usually but the 3 stripes don't really gel very well with a black and white striped kit.
Best kit of all time in my opinion was the 1997/98 season (the one where we lost to Real in the final)
Best away kit is probably the current one - I really like it.
For nostalgia, the away kit we wore to win the champions league.
