Barcelona's new recruits have raised hopes for the second half of the season. However, not all of them will be able to be registered for the international tournament.

FC Barcelona have completed a winter transfer window for the history books, in which they have managed to complete four new additions that will serve as important pieces in Xavi Hernandez's scheme.

Now, although they are players of hierarchy that will bring imbalance to the new offensive of the team, not all of them can be registered in the Europa League, so between Dani Alves, Ferran Torres, Adama Traoré and Pierre-Emerick Aubameyang, one will have to be left out of the European competition.

According to article 46 of UEFA's regulations, clubs can only register three new players in the winter window. That is why one of the four new faces who will be at the Camp Nou will have to miss the international tournament. Barça will make their debut on Thursday 17 February against Napoli, after two decades without knowing any international competition other than the Champions League.

This Wednesday is the deadline for the club's board of directors to make a decision regarding their players. In a first analysis, everything indicates that it will be Adama who will be left out.

Xavi does not have many replacements for his full-backs, and Dani Alves, although 38 years old, is still a solid and experienced option at the back. In addition, the 55 million euros paid by the club for Ferran Torres will secure him a ticket, as will Aubameyang, who has a goal and is a necessity for the Condal side.

In addition to this, Ferran Jutglà and 'Ez' Abde would also be left out. Even though they still have a reserve team record, they haven't been at the club for two years, so if they were to be signed, they would be counted as new signings.

This is an even more sensitive loss for the coach, who has enjoyed the good performances of both youngsters and has been a spectator of the good performances they have had in the first half of the campaign.

Must Win encounter vs Napoli:

Barca knows they must secure a ticket to the last 16 by all means necessary. However, Recent visits to Italy have not gone well for the Blaugrana, with the 3-0 defeat to Roma in the Champions League the most painful in recent years.

The new players can bring constant danger to the opposition goal, and a solid approach against the Neapolitans can ensure a good advantage in the return leg at the Stadio Diego Armando Maradona.
