One of the Achilles heels of Barcelona de Valverde has been this season the defense. The Catalan team has conceded in the first round 23 goals in 19 games played, more than one per game (1,2). A performance that leaves the Blaugrana team away from the records of its most direct competitors for the League title. For example, Real Madrid and Atlético de Madrid have fitted almost half of the Blaugrana (12 goals against both teams) while Sevilla has received 18. LaLiga Santander* Data updated as of January 17, 2020 These records are even more surprising and worrying when compared to those of the same team in the previous two seasons in which Barcelona reached the equator of the competition with only 9 goals conceded in the 17-18 season, the first of Valverde, and 20 in the 18-19. One of the most urgent challenges that Quique Setién must face in his stages in Barcelona is to solve the defensive problem of the Blaugrana team. And it must do so with a shortage of troops, because after the march of Jean Clair-Todibo as assigned to Schalke 04, the technician will only have three centrals in the first template: Gerard Piqué, Clément Lenglet and Samuel Umtiti. Considering that defense is not one of the great virtues of Setien’s teams, The technician is faced with a key challenge that he will have to face with effective counting, especially as regards central defenses. Piqué and Lenglet point out as an almost immovable starting couple, as it has been throughout the season, but with the peculiarity that competition has decreased. Todibo left on loan to Schalke almost at the same time that Setien landed and Umtiti remains unreliable after his physical problems as evidenced in the Spain Supercup disputed in Arabia.The resource that Setien has left is to look at the subsidiary and reel Araujo, This season already debuted with the first team.In any case, a difficult ballot and that seems to prevent the implementation of new systems, such as three centrals unless a player from the center of the field becomes a central one.
