Sorg, who appeared before the press with manager, Hansi Flick suspended for two games, said Barcelona did not start the game focused against Leganes.
He added that the Blaugrana failed to beat the visitors despite creating chances.
Sergio González’s early goal gave Leganes all three points against the hosts.
“The team did not start the game focused and that led to the goal,” Sorg said at his post-match interview.
“The team have found it difficult in the league and despite having chances we failed to take the win.
“Defeats like today are hard to take but it’s all part of the process and we have to work hard so things turn out as we want them.”
