What you are saying to an extent is correct if you are surrounded by people who are into football. In my country people are crazy about cricket and the local media does keep us updated. Apart from cricket, football does intrest me but it is not easy for me to keep a track of all leagues. That is why I follow only one league and place bet on matches where I feel confident. In case of cricket I am not selective or saturated to one league. I am following multiple league as I am more updated due to my surroundings.
I am a fan of football myself but I don't really follow many leagues but only the major ones.
I think getting updates on any sport has become very easy these days since there are sites out there which do these jobs.
Especially doing live matches, there are sites which gives live updates and so I think getting updates for matches which are not live yet should be fairly easy.
With the use of internet you can easily locate the update that you wanted to know, just be very careful in sorting those trusted website as there are website that just alluring readers, chances that update are only to gather attentions and to advertise gambling site that they are link and have referrals, even you see available information never to dwel in a single site but to check other venue to make sure that you'll be able to confirm or to have better understanding before deciding to place your bets.
Yes you are right that mate we need to be more careful as we are all know that everytime we use an internet we can not say that we are safe or we cross along the trusted and legit information. Because nowadays there are many fake sites or let say fake information so we need to be mindful and watch our every move because once we spontaneously do such thing without thinking then we will loss.
That's going to happen if you will not extend your efforts to do your own research, not everything around the internet is legit as I mentioned and even the news came from a legit site there's always other things that you needed to check especially if you are going to use it as reference when playing/betting. More on how you understand the game and how you will link your knowledge to make a possible edge and have a good result with your game/bet.
