The biggest disaster so far is Banja luka losing to Santa Coloma so much. Nobody expected this to happen in the qualification especially about a team that reached the playoffs last season. To lose so heavily against an amature team do badly its just unrealistic. I think that they wont qualify for sure after this match
No team should be underated because qualification stage is always marked with upsets and drama another thing that motivates smaller teams to give their best when it comes to qualifying for the top completion is that of the monetary involvement getting to the group stages of the competition will be financially good for the smaller teams
There is no small team when it comes to football especially in this preliminary stages of the tournament because teams considered as small will like to prove a point so I expect that every team that is playing at this stage of the competition play with all level of seriousness because upset is bound
