There is one manager on my friends list and we happen to be in same league now in level 4. He has the second best team in the league and I have the best team. To my surprise, he started supporting my opponent every time I play so I lost three matches in a row. I didn't bother but some time later I decided to pay him back with his own coin, and now am currently two points behind him as he has lost a match and drew two. Later today I found that he has removed me from his friends list... what a jerk! he can't take real competition, anyway the league is far from over and I hope to let him know, I have to play him the day after tomorrow, a battle for first place.
