[Question] - Downloading Matches

^Title. Is it possible to download the .mp4 or whatever format it is from an ufficial source? If not, it' s because for technical problem (to keep server load at minimum etc ) or there are copyright infractions for that?

Let' s not talk about unofficial tools/sources, i am asking for ufficial ones; only exception fan-made sites for downloading them.

Context: i have a terrible connection, so i was thinking about downloading the videos when they were avaiable so i could watch them lagless and high quality. Not like i can watch live streams since the day time is in myym sfavor...
