Xavi probably understands Barcelona's weaknesses very well. But still he could not stabilize the team completely. Barcelona had some trouble scoring in the previous season. But after Torres and Aubameyang came into the team, this problem was greatly reduced. But Barcelona's defense was weak. Although the forward is strong, Xavi has not yet strengthened the defense. Maybe Barcelona will add a few more players to the squad this season.
It should be with the arrival of their new players at this time even though they came on a free transfer but they now have to feel relieved because they are more able to maintain stability in defense.
We know that the current Barcelona defense is very fragile, apart from that the players there are quite old in my opinion so there must be an update and Andreas Christensen and
Franck Kessié has actually been a good thing for them.
