I wrote a small add-on for the wordpress leaguemanager plugin. This plugin lets you specify your team name and then will give a drop down of all opponents. You can then selected the opponent and see all results vs that opponent. To install download the leaguemanager-opponet-search.zip file and extract the one php file to your /wordpress/wp-content/plugins directory. Then enable the plugin. Then finally add the following shortcode one of your pages:
[opponentsearch team_name="My Team Name"]
You can see an example of the plugin on the ECS FC website.
This plugin has no support, so please don’t ask.
