I do the same, I like to track how they are doing, support them and then they support me in return, I do not expect support in return and I never ask for it, even though we are league rivals we still support each other, he beat me but we still support each other, so mainly for possession bonuses and supporters and also I like to check on how they are doing in other competitions and support them there.
