I rarely watch my games these days because to me, the risk of a troll is too great and the algorithms seem to favour the absent Manager especially if that absent Manager is the away team. I finished 2nd in the league last season and watched only 1 game.
Today in the Cup I logged in as I was away and it was 0-0 from first leg. I was 2-1:down to an absent Manager and getting battered then he logged in and suddenly the whole game changed in my favour. I scored 3 quick goals and the players ratings suddenly improved considerably. I ended up winning 6-2.
Proof if ever that logging in is bad for your team (in my experience anyway).
