On PC version, In the main menu there is a button that says: "REPLAYS". It records the games you play into files you can watch from different perspectives. Click that and choose a round you want to watch. It can be a bit buggy, sometimes you have to wait a few hours after a match until a file can be played without errors/crashes. Some buttons/shortcuts are not shown and may be found in keyboard settings in options. I don't know if console versions has a replay mode. Good luck!
