So far this season I have a record of 10-3-3. My record against players I am friends with? 0-0-3. And they are all in the same league as me, and I am 3rd while they are 5th and 8th respectively (The third loss came in Champions League), so it's not that they are just much better teams than me. My team simply either forgets how to play against my friends, or their teams magically play better against me. This was the case last year as well, as I lost two very important matches to one of my friends.
Is this typical? Are friends more likely to "upset" other friends? Because if that's the case wouldn't it be wise to not have friends in the same league? It's getting really annoying and I need to find out if it's something in the algorithm where the only thing I can do is unfriend them, in order to avoid giving up any advantages.
