Checking other managers stats

Why can't we see the full stats of another manager or friends other than in a game against them, I would like to see how well they are doing in their own league, cup and champions league section if it isn't the same as the one I'm also playing in. (Hope this makes sense)
Eg Bob is level 3 and becomes friends with Tom level 6, how can Bob see the current competition status/results of his friend Tom, I know he can look at league standings when reviewing Tom but doesn't see his cup or champions league status, and maybe also look at other manager statuses in other competitions too or is that too much info to load
