Tagging any team as a small will absolutely do you more harm than good because as it stands now I don't think any team is little because football can be ruthless sometimes and the games that you feel is going to be an easy win for the supposed stronger can change within matter of second and favour the inferior team, I mean we all saw how it happened with the Chelsea and PSG finals.
There's absolutely nothing like big team or average club when it comes to main tournament. We've seen how it looks like to watch teams coming up and perform at the big phase. Chelsea vs Paris Saint-Germain in the club world cup final, the Blues was underestimated and look at where they have elevated to? Thrashing Les Parisiens 3 nil without allowing PSG to even hit just a goal, definitely a big win for them.
Enzo Maresca go home with two major trophies, the Conference League title, where we watch him won against Real Betis and coming to face PSG in the club world cup, they won it with full confidence. This is the kind of team that's cooperative and formidable pattern follow up.
