I think it is very difficult to handicap more then 1 League actually.
The teams that you mentionned are the teams that the majority of the average gambers put money on because everyone is aware that they are good. Sure they win a lot but the odds are so low that there isn't that much profit in the end. More people should stick to their own home League or the leagues they follow closely. If you watch all the games and know all the players and the detailed facts, it is much more likely that you are able to find the good value plays.
I've been handicapping the Belgian League since the Beginning of the season
on this site and I've been posting my top plays for 2 months
here.
I love the betting community and am very gratefull for the guys like Brewers, MistaFlava, Procapper, SpreadBeater and all the other great cappers to post their plays and writeups on the NBA and NFL because I have absolutely no clue about those sports myself.
I am still looking for some reliable sites with writeups and picks that are concentrated on other soccer League. It would be nice if someone could post some interesting links.
I got 2 links for those who are looking for some help with the Belgian League!
