why do managers leave their own group during week? cause ive seen , mostly the top 100 world groups, with few managers and when the weekend aproachs there they are again....and during the weekend we see them with few points....mostly of them get 12 points only, that means they won all the games during weekend....and then on monday when we look into those groups....pufff.....only 1 or 2 managers left there.....all others had gone somewere else, and as soon as the weekend aproaches there they are again.......with 0 points......why do they do that???
