I use this website, fantastic stats in a very easy format.
[
www.soccerstats.com]
For example Wolves have played 6 home games and have a 100% both team scored stat, with an average goals per game of 3.5.
Burnley have played 6 away games they have scored in 4 and conceded in all 6 and have averaged 2.83 goals per game.
I would suggest this is a very good BTTS, perhaps Wolves and yes, 2.5+ or 3.5+ punt.
Every league in the world, and another example, these are the average goals per game;
England - Premier League 3.15
Germany - Bundesliga 3.44
Netherlands - Eredivisie 3.29
England - League One 2.54
Spain - La Liga 2 2.37
Scotland - Premiership 2.54
So if its a goal based bet, there is more action in the top three
ps Wolves v Burnley bound to be 0-0
