All Answers
<apex:commandButton action="!{Save}" value="save"/>
to
<apex:commandButton action="{!save}" value="save"/>
In the VF code, the error you're getting is because you have
action="!{Save}"
it should be
action="{!Save}"
Then, in the save method, you are querying the record, which will overwrite any input that the user has made. The record will be saved unmodified.
In fact, everything you want to do can be done using the standard controller. You don't need the "worldcup" class at all. The code in the next post shows how to do this.
