To become a champion I think Atalanta is very difficult to expect, here is not the Europa league that he can master like last season, here is the champions league where not a few teams are very extraordinary in making their way in the much stronger champions league, seeing Atalanta's performance from the draw match against Arsenal it is not worth counting in my opinion, we also know how Arsenal's performance is always inconsistencies in the champions league, we will see that view when Atalanta can reach the semi-finals, I really doubt it will be like what happened to Dortmund last season, can it have the same fate? I really doubt it.
So far, I don't see something special with Atalanta. What makes people to expect Atalanta be the champion in UCL? If people assume winning the Europa league last season to be the reason of Atalanta reaching the final UCL, it is something nonsense. Sure, the level of Champions League and Europa League are different. Champions League is much harder, we have too many strong teams here. Even some teams become the favorite to reach the final (Real Madrid, Man City, Bayern Munich). These favorite teams is surely stronger than Atalanta.
However, I don't underestimate Atalanta. It doesn't mean Atalanta will have 0 chance to survive. However, if we consider its current performance and the squad quality, it is unlikely to see Atalanta in the semi-final or final UCL. I personally assume the realistic target is to reach the quarter final. If Atalanta can qualify the next round, they will have a chance to go to quarter final.
Atalanta winning Europa League indeed good achievement but i don't think they will be automatically became an the favourite in this competition because just like we all know that Champion league is very different compared to other competitions and it's hard even for strong teams to gets the trophy even Guardiola has been admitted Champion league is the hardest competition in Europa
The draw result from Arsenal indeed has successfully to boosted Atalanta mentally although i personally didn't satisfied to see this result because they have good chances to beat Arsenal but i think draw against strong team just like Arsenal is good achievement for Atalanta
I think it's too far to talking about champion possibility for Atalanta because they are not the favourite in this competition besides that there were plenty of big teams who deserved to called as champion candidates rather than them and if we talking about knockout stages i think they have to try harder especially besides Arsenal Atalanta has more strong opponents just like Real Madrid and Barcelona
