The 13 Barça B players Enrique has called up

FC Barcelona returned to training this Wednesday, leaving behind their summer holidays.

Luis Enrique Martinez will carry out his work sessions with players from the B team during these first days, given the fact that the international commitments of the majority of his first team squad, will lead them to join the group at later dates.

Luis Enrique called on 13 Barça B players to make up the numbers for training, six of which were signed by the club this summer.

Here is a run down of the players that participated alongside the first teamers.

Jose Aurelio Suarez. Goalkeeper.

20-year-old Asturian keeper, who joined Barça in 2011, at the Juvenile B level. Last season he also joined the first team's pre-season and travelled to the USA with them. Valued highly within the club, Barça have rejected offers that have come in for him from teams in the Spanish first and second divisions.

Marlon Santos. Left-sided central defender.

Defender that joined from Fluminense this summer on loan, with an option to buy fixed at five million euros. His incorporation to the first team's training sessions was planned since his arrival, so that the Barça manager can monitor the 20-year-old Brazilian's abilities up close.

Borja Lopez. Left-sided central defender.

21-year-old Asturian defender that arrived on a free in the last winter transfer window. He is tall (6'3"), has played in the French and Portuguese leagues and has represented Spain at youth level. 

Jose Antonio Martinez. Right-sided central defender.

The Andalusian defender is 23-years-old, and joined the club on a free transfer this summer from Sevilla's B side. He is a Barcelona fan, and this played a part in his decision to opt to accept the Catalan club's offer ahead of renewing his deal in Seville.

Francisco Jose Perdomo 'Nili'. Right-back.

A 22-year-old from the Canary Islands, he is a new arrival from Las Palmas, where he played eight games in the first division last season.

Gerard Gumbau. Defensive midfielder.

The youth product is becoming a familiar face amongst the reinforcements called upon by Luis Enrique. Last season, he was able to make his debut with the first team in La Liga and the Champions League. He is on the verge of making the leap to Camp Nou, and he is expected to be called upon severla times by the first team this season.

Ignacio Abeledo. Left-sided central midfielder.

20-year-old midfielder who joined from Betis B, considered to be the gem of the Seville side's youth setup. Barça signed him this summer, though he was already close to arriving in the winter. He has represented Spain at under-17 and under-18 level and already made his debut with the Betis first team.

Alex Carbonell. Central midfielder.

He began his career with the FC Barcelona school, passing through the younger age groups. He was released at the Infant level in 2011 after failing to make the cut. He joined Cornella, and rejoined Barça two years ago. He renewed with the club last week. He can also play as a winger and as a 'false nine'.

Carles Aleña. Central midfielder.

18-years-old, he has been at the club for over half his life. He began his career as a winger, but with time, he retreated on the pitch to the midfield, where he is able to exploit his qualities, such as his vision, attacking the opposing area, and good long-range shooting.

Juan Camara. Left winger.

22-year-old forward, who has just renewed his deal with the Catalan club for a year, with the option of joining the first team if Barça renew him at the end of the season. He came from Villarreal B in 2014, and his ability to play as both a winger and as a creative midfielder stand out among his qualities.

Alberto Perea. Right winger.

Born in Albacete 25 years ago, the forward arrived at Barça in the winter. He has already played 13 times in the first division with Rayo Vallecano. Last season, he played 16 matches with the B team, scoring twice and provided four assists.

Jesus Alfaro. Winger.

Signed this summer from Alcoyano, the Andalusian player scored 10 goals last season in the second division B. He is 25-years-old, versatile and can play in any of the front three attacking positions.

Marc Cardona. Forward.

He is a 19-year-old natural centre forward, signed this summer from Atletico Sanluqueño, a club with which he gained promotion to the second division B level, and became the revelation of the third division last season.
