Well football is quite bigger than that now because there are some teams that are very stubborn and even if they come to the Champions League other big teams will definitely feel their pressure to a point because as it is now in football I don't think there is any small team available and even the likes of bodo will indeed cause minor or even major upset to some of the big teams.
No team makes it into the champions league without trying to make their mark. Some of these teams know they have no means to lifting the trophy and so, they look forward to doing some good phase in the league. Most teams don’t look to be eliminated in the group stage and others just wish to see the round of 16 over before finding their way out. That’s why it’s a league for champions, you only make it this far by being the best in your local league.
