Not sure but last season I didnt watch any games for all three of my teams (level 31 , level 25 and level 15 ) and all 3 won the league , 1 won a cup ,all 3 made at least 1/4 finals of CL. You might argue I could have won more cups or a CL if I had watched and I would say I might not have done as well as I did if I watched. I guess we will never know for certain but I am happy not watching , training 3 teams takes enough time as it is.
