I live in Spain mate and I do not agree, La Liga is better than it used to be but there are still a fair amount of no contest games and ref calls that seem amazingly biased (how Barca had 11 men on the field at the end of that last game with Aletico is beyond me).
Re the award itself, it's a bit flimflam now, as others have said most years it seems its a golden boot and by default the award goes to Messi
I don't understand it, is Messi a brilliant, once in a generation talent with an amazingly goal scoring record? = absolutely
Has Messi done anything for Barca or Argentina results wise that they wouldn't have or historically have done without him (Barca winning La Liga for the 26th time is like saying a player made a difference for Celtic)? = not really, in the last 7 years (Messi's prime) Barca has one CL. For country it's clear Ronaldo, Bale and Modric have done more for their national teams.
The fanboys will go crazy but if it's a golden boot award, great, give it to him. But again, players like VVD probably way more impact on their team (and I hate the victims)
