They are wasting their time. They can never prove it unless the players confess. Remember the case of a former Liverpool goalie who went free despite all the proofs ? There have always been suspicion of match-fixing in the English league before and after that case but it is almost impossible to prove it.
Thing is though, unlike individual sports like snooker or golf, it's practically impossible to fix the results of matches unless there is huge scale complicitness (the whole squad would have to be in on it).
If anything it will be tangental stuff like first throw-in, or no balls in cricket.
I guess keepers are the main exception, as history has shown (Segars, Grobelaar etc).
