Dear Contest holder,
I have uploaded my idea of your concept which is playing with the letters in the logo. I placed here different combinations of colours that you can chose from. Blue is the colour you prefered and green is connected to the playing field.
The font is sans serif in italic ( and bold in case of word soccer) - it is showing the movement and also the power of itself. ACCC is placed in the rhomboid to be easily readable both from horizontal and vertical direction - everytime it begins with AC and the rest CC. Soccer is then placed horizontaly with different thickness of the font in the whole row - this ensures the good readability of this word although the part of it is inside the rhomboid.
I hope you will enjoy it.
