In college football, they are very liberal about jersey numbers unlike the NFL.   There seems to be no regulations on who can wear what.\n\nEven players who are both on offense or defense can wear the same #'s like Cal's Young brothers who both wear #88 and are both offensive players.\n\nIn the NFL, there are strict rules like only #13 can be worn by Kickers and Quarterbacks, or recievers and backs cannot wear single digits.

If you saw the games there was so much paper and debris on the field it looked more white than green.It was done to provide contrast for officials of the game to make sound dicisions and for the goal keepers to help prevent injury.

a team's uniform must not interfere in color with the opposite team

Because that is the color of the National Team, called "Azzurri".\nThat is an historical tradition: before the creation of the Italian Republic, the Italian Regal Family (Savoia) had color "azzurro" (kind of blue) in their flag and that color was adopted by the soccer National Team to respect the Regal tradition.\nSince then the color has been kept in the Italian shirt, even though it is not a color present in their National flag.\n\nNOTE: the Italian flag is green - white - red and NOT red - white -green

Which shirt? their main color is black and white and their alternate jerseys are pink

Its not a superstition thing as much as it is a cosmetic thing.  Players who wear high socks do it as an alternative to tucking the pantlegs under the legs themselves.  This way there is extra padding by the knee as well as the socks are all the way up.  The look is solid, and the comfort of not having the pants moving all over is great.

I have heard that the reason that Germany wear green as an away strip is as a mark of respect to Ireland.  \n\nIreland were the first non-German speaking country that would play an international against West Germany following the war (in 1950).  As the national colour for Ireland is green, Germany said that they would have their 2nd strip in this colour as a thank-you.\n\nThis year Klinsman has changed this strip to red as wearing a red strip  statistically produces better results across the sporting world.

I AGREE WITH ALL THE ABOVE ANSWERS.BUT IF U R WATCHING THE MATCH IN THE STADIUM, U MIGHT BE KNOWING WHO IS THE GOALKEEPER OF WHICH TEAM. WE CAN FIND THE HOME SIDE BY SEEING IN WHICH SIDE THE GOAL KEEPER IS STANDING.

THIS IS DECIDED FOR 2 REASONS:\n\n1.-The team will play away or\n2.-The color of the jerseys of the  other team\n\nAll the teams have 2 jerseys in several occasions 3, 1 jersey for the home games and other for the amay games, if the jersey of the team has the same color of the jersey of the another team must be changed.\n\nHope i answer your question\n\nAtt Juanpapas8

It is sometimes quite confusing!\nGenerally the offensive player cannot wait for the ball behind the last defender not counting the other team's goalie.  If that offensive player shows just a little part of his body or more behind the imaginary line where the last defender is before the ball is kicked and sent forward.\nThe confusing part is whether the offside player is actively or will actively play the ball or not determine whether it is an offside or not.  To me even though the offside player is not actively playing the offside ball, he can distract the defender enough to affect the play, it should be an offside.\nIf the ball is touched or deflected by the defender before the offside player receives the ball, it is still an offside.  But if the defender is trying to control the ball but the ball somehow gets through him or her, it is not an offside.  \nMay be better not to have an offside rule.  It should be the defenders' job not to leave a guy unmarked close to his goal.\nJust me!

It is to help with the offside calls.\n\nAs noted by at least one, usually a lot of fields use different designs for purely aesthetic reasons, including circles, diamonds, etc.   As you've noticed, there has been a marked lack of variety in the field designs for the World Cup.  Only the striped patterns are used.

To be outstanding among the other players. So the referee wont be confused. If the goal keeper is wearing the same jersey, the defender can use their hands to block the ball if the referee or lines man are not looking carefully. Just my point of view. =D

In the FIFA World Cup the team that is considered the "visiting" team is the one that changes the uniform. Australia changed because the match was Brazil x Australia, if it had been Australia x Brazil, the brazilians would have played with their reserve kit.\n\nWhether the match is "Brazil x Australia" or "Australia x Brazil" is determined in the World Cup draw months before it starts.

I heard this explanation during a telecast:\n \nMost teams have 3 sweaters; one white, one dark, and a third alternative sweater for special occaisions (e.g. national televised games, holiday games, etc).  The third sweaters are also dark, with special graphics.  If dark jerseys are for away games, the teams would have to pack both the standard away and the alternative jerseys.  If white is the away color, it makes it easier; simply pack only the white jerseys for road trips.

It's a tradition to exchange jerseys with an opponent you admire or respect. Players go up to a member of the opposing team and ask them if they're willing to trade. Most often players are open to it. They keep the jersey they get as a souvenir of the game.

If they're wearing colors that are close to the home team they are playing, I thought.
