足球开场怎么握手？
这是国际足联对开幕战握手要求的官方解释： Opening Ceremonies： Handshake 开幕战中的入场仪式、入场寒暄（通常也就是握手） Handshakes between players are not compulsory， but should be done. The following guidelines apply to opening games of a tournament：-
1) Players enter the field separately， with their managers behind them (and in the case of team captains or joint captains at either end of the field);
2) After each player has come onto the pitch， they must shake hands with all of those present; and
3) Managers may only hand out prizes for first place on the day of the final. In the event that more than one game determines the champion(s)， this decision is left to each specific competition’s organisers， as long as it's clearly explained beforehand. This does occasionally happen — e.g， the UEFA Cup winners were announced immediately after the second leg of the finals， which was shared by two teams， so both sides were awarded the trophy.
So basically：
* If you play a friendly， there will likely be no official handshakes； however， if you have an international match against another nation’s national team – such as England vs USA – then these rules definitely apply， even though FIFA would probably prefer that none happened at all. So unless your captain specifically tells his men not to engage in any pre-match rituals， expect some sort of awkward handshake ritual. And don’t blame anyone else if you get a bit emotional about it…
