Laliga title race is indeed difficult to predict because Barcelona, Real Madrid and Atletico Madrid have always been strong candidates for Laliga champions. other clubs may not have a chance to shake off their dominance. like Valencia who used to be strong competitors but in recent seasons they have not played well and their performance has dropped drastically. next season several big clubs began to clean up such as Barcelona, Real Madrid and Atletico Madrid.
I disagree with you on this, La Liga title race can easily be predicted knowing to well that two particular teams have been in the dominance of the league for a long time. Real Madrid and Barcelona will always be at the first line when we talk about teams with the winning percentage, ATM have experienced a lot of ups and downs so I don't see them pushing too hard for the league. Valencia used to be contenders too but they are not really in good form lately so I think Real Madrid, Barcelona and ATM have a better chance of winning the League.
ATM won it previous year, so it is not always that easy. Obviously you could say Madrid right now and would be in big probable chance to win, but it will be not a high odd neither. Not like we are going to see 6.50 odds for Madrid to win, it will be like 1.80 or something, or at the very best a bit over 2 if you are lucky, in that case you could play for Barcelona, which would be over 2, and if either wins out will profit.
But, I believe that it is going to be one of them under 2, probably Madrid. If that happens and ATM wins again, then you lose it all, and people do not wager tiny amounts for outrights, league titles are usually wagered a lot more.
