Did FC Barcelona​'s US Tour reveal how frail Luis Enrique's defense is?

FC Barcelona's US tour made it clear that the team have absolutely no problems creating goalscoring chances, even though two-thirds of the Catalans' three-man attack did not play. However, it also threw up some defensive frailties.

During the game against Chelsea, it was clear to all that the Blues' strikers found it far too easy to get in behind Barça's centre-backs, especially Bartra and Mathieu. Things improved somewhat when Piqué and Vermaelen took over, but it is clearly an aspect of their game which needs some attention ahead of the European Super Cup.

The US tour also threw up a series of problems that FC Barcelona have defending from set pieces, which is strange considering how solid they were last season. Luis Enrique admitted as much at a press conference and highlighted "how whimsical football is sometimes" with this sort of thing.

The Spaniard said he is working hard to improve that aspect of their game and that the easy option would be "to sign taller players, but that would mean changing their playing style", something that is non-negotiable at 'Can Barça'.
