What about Bologna, though? recent arrivals on the block. They'll will feel the heat. Depth of their squad? Not close to the big boys now. Early departures are probably possible; fatigue will set in
Still, they qualified for their place. Count them neither totally nor completely. They give the tournament new vitality. They have heart, strategy, the element of surprise even while they lack substance. Their day could bring an upset
What is there to worry about Bologna and or the newcomers? Are you worried about them losing or something else? Because anyway, if they get a loss I think it's a natural result because after all, the competition in the Champions League is about the top teams. Indeed, at certain moments there will be surprises that occur when a mediocre team is able to advance further, but in reality, this doesn't happen often and is quite rare for it to happen either. So yes, if Bologna are eliminated early I think it's natural, due to the fact that Bologna also have a new coach who will certainly be a differentiating factor also with their success last season with Thiago Motta.
With such considerations, then I think there is nothing to worry about because at least, the concern is about the top teams that may still be in doubt for example like PSG will play without Mbappe next season. I think it would make more sense when worrying about a top team that doesn't seem to have a chance of going further, if comparing a mediocre team to a losing result, because that would be natural.
