Leganes coach Asier Garitano believes Barcelona are stronger this season without Neymar.
Barca defeated Leganes on the weekend.
"Compared to last season, when they still had Neymar, they've changed a lot," said Garitano.
"From 4-3-3 they went 4-4-2 to 4-3-2-1, but most of all, the summer problems of Neymar's departure were beneficial elsewhere, because they made Barça more a team than before.
"They are more compact. They always keep possession, but are stronger defensively."
Garitano was speaking to Tuttosport before tonight's Champions League 0-0 draw between Barca and Juventus.
