May be it's the background (so blue) that make the shirt look a little bit heavy on yellow. The design, as Diss said, not very spectacular but lots of time, team uniform is hardly special. One good thing about this uniform is the opponent may not be able to see how they hit the ball. I miss the tennis ball the first 2 times I look at the pic.
Guga didn't get rid of that hat, erm, may be he had a very bad hair day?
