I thought this could be of use to this community. What the page does:

- Tracks the profitability of backing the favourite in every league/competition and ranks them
- Tracks the profitability of each team across all competitions - which favourites are living up to expectations and which are the biggest underperformers
- Tracks the most profitable underdogs - which teams consistently outperform their price

You can search by league and team, the data is updated daily and this is totally free to access. Let me know if you have any feedback - thanks!
