there are tons of tipsters and all you need to do is to check a platform for tipsters , maybe try tipstertube , pyckio and blogabet
you will find a lot of good stats but most of the time you won't achieve what they are achieving , the majority of high yield tipsters tip obscure leagues where you will get limited fast
also the odds difference may be huge for some picks especially when you are following a popular tipster that has hundreds of followers

all the sites I mentioned have stats for their tipsters but you are the one who can find out if they suit you or not ( depends mainly on your available books )
