Up to seven times, the opponents scored on the second post, one of the team’s weaknesses, especially on the defensive left side. Antonio Puertas and Azeez with Granada, Óscar Plano with Valladolid, Mata del Getafe, Rubén García de Osasuna, Marc Bartra del Betis and Arturo Vidal last Saturday with Barcelona. The meeting against Valencia, which marked a negative turning point with Pablo Machín on the bench, was resolved by a penalty by Víctor Gómez trying to defend the second suit.If the second suit has been lethal, no less impressive has been the lack of attention when defending the first suit. Luis Suarez scored on Saturday, as did Karim Benzema at the Bernabéu, Borja Iglesias with Betis, Santi Mina in Vigo, Ramis with Eibar or Budimir with Mallorca. This data stands out especially in the time of Machín, in which Espanyol played with three central and average an average of 20 goals received in 10 games, by 14 by David Gallego in eight games.On the other hand, and despite trying to attack from the sides, only Espanyol has managed to score somewhat center in play, which was the one that Jonathan Calleri scored against Osasuna. The rest came from penalty kicks, in stationary shots, fast transitions or individual plays, an aspect that reduces the performance of the team. With 36 goals against, Espanyol dismisses the first round as the team with the weakest defensive system of the 20 LaLiga and its recent history: in the 2015-16 campaign, the worst in terms of goals received refers to a total of 74, at this point 30 had been fitted; and in 2003-04 they took 33. A deficit that is summarized in examples especially in Cornellà-El Prat, where Real Sociedad (1-3), Granada (0-3) or Osasuna (2-4) managed to undress the Espanyol in hilarious matches from the defensive point of view.It is striking that of those 36 goals, 35 have been from within the area, a very high percentage. The only goal received from beyond 16 meters was made by Mikel Vesga in San Mamés. The rest, counterattacks finished a few meters from the goal, penalties or shots after centers from the sides. It is in this facet of the game that Espanyol has been more fragile than other teams, unable to defend the lateral centers well.
