Silver and gold match packs, and purple players

Translate

Before the last update that caused me to start over again I managed to get quite a few silver and gold match packs by having a closely scored league match but only getting bronze now. Anyone worked out the new method as battering them doesn't work either?

Same issue with purple players rewarded from winning WC, had 2 purples out of 12 reward players last time, had 11 silvers and 1 bronze this time so far...
