I recommend LiveFox pour firefox wich is a very friendly match viewer. It allows to follow the matches of your league opponents as well as the evolution of the leaderboard in your league in real time.
You can also follow the match of your friends. You can save your friends so liveFox will then open their matches automatically each time. It's very useful.
The interface is pleasant and specifies the exact type of opportunity (type of special event, right, left, center, penalty, free kick direct or indirect etc.).
To install click on "install" on the left of the homepage or the link provided.
Here is the match viewer of htplus.
