Xavi really stabilized Barcelona's game in a short time and raised it to a higher level.
The real results of his work will be seen only next season and that is why this match with Napoli came too early for them.
Barcelona still have chances against Napoli but realistically Napoli is closer to moving on to the next stage of the competition.
Barcelona have started this season very badly, and doubt and unrest have crept in among the players, and because of that the players are not yet showing everything they can and know.
Xavi has brought significant changes to Barcelona during his tenure this season, but I cannot expect him to achieve perfection in his first season as Barcelona coach. Now Barcelona has returned to the top 4 of the Laliga standings and it is a good achievement with him after previously Barcelona could not be expected.
Xavi has certainly done well with the current squad of Barcelona because in this same season before he came as a coach we didn't even believe that Barcelona might be in the top six.
Now, I know that Barcelona is not doing very well but still doing better than before in my opinion and we also cannot expect Barcelona to perform as they did in the past when the squad was really great and a lot of players were in their prime.
About the Europa League competition, I can think otherwise with you even though Napoli will be playing at home. The first leg Barcelona played better and I also really believe Barcelona can beat Napoli in Italy to qualify for the next round. The supportive thing at the moment is that Barcelona's form has improved and it's a good hope to see them beat Napoli although many people are not sure about that.
But against Napoli, I don't think Barcelona will be able to win because first of all it's an away match and they don't have any advantage from the home match and secondly Barcelona has a lot of problems in their defensive line. And I think Napoli is going to exploit it.
