Atalanta in its own domestic league is still quite overwhelmed in getting its best position at the moment, so I don't think that Atalanta will be able to trouble Liverpool in the Europa League this season because Liverpool is a very strong team in the Premier League and has also shown its strength in the Europa League this season. This means that Atalanta may be just an ordinary opponent for Liverpool in the Europa League quarter-final match.
Atlanta deserves some accolades as they have so far tried having gotten to this point of the Europa despite the whole fact they they haven't been in their best form or been the best team either, they are still in the Europa and I think their Europa performance can be seen as been much more better than their performance in their domestic league, invariably they are prioritizing the Europa much more.
Liverpool will actually not see them to be an issue as they actually don't appear like one to them in the fact that Liverpool is in a much more better form than Atlanta in the Europa , a d so meet with them can only means that may be the end of Atlanta's journey through the Europa but with Liverpool it's still some miles ahead because after Atlanta comes other teams they will have to tackle before they will be able to lift the trophy by the end of the Europa league competition this season. Atlanta considerable can now focus on their domestic League after this.
They will be hopeful in the fact that they may be able to get something out of their domestic League, probably get to be able to qualify again for the Europa by next season and if they are much more improved by then, they will be able to see if they can. Make something really good out of the Europa next season and nit just their domestic League alone. Theres still much room for Atlanta but that will have to be by next season.
