The blanket theory is a recurring problem in the world of soccer. If a team defends well, it is generally difficult for them to attack. In contrast, teams with large offensive flows tend to have problems behind. Pellegrini encountered this problem at Betis and was able to find a solution in the second round of the championship.
Because the data are resounding: Betis has gone from conceding 32 goals in the first 19 games of the championship to receiving half, 16, in the second round that ends this weekend. However, the offensive production has not been diminished at all, since Betis, in the absence of a game to finish the championship, only adds a little less in the second round, 23 times 24 in the first round.
Defensive problems have been an unsolvable drag on Betis in recent times. So much so, that in case of not conceding or receiving only one goal in Vigo, Pellegrini will achieve a milestone that no Verdiblanco coach since 2007: finish LaLiga with less than 50 goals against. It was in 2006/07 when a Betis that was saved on the last day managed to close the course with 49 goals against. Now, in addition, the improvement in the defensive balance has been accompanied by an evident qualifying jump.
