Senior Real Madrid game director Mesut Ozil made a dig at Barcelona after their exit from the UEFA Champions League.
La Bluagrana's chances of European glory are over in midweek as they were eliminated in the quarter-finals by Paris Saint-Germain.
This result means that Barcelona are almost certain to end the campaign without a trophy as head coach Xavi Hernandez he is moving this summer.
Xavi's side head to Madrid this weekend for their final El Clasico of the season with only pride realistically to play for on the back of a frustrating week.
Ronald Araujo's red card against PSG was followed by another line dismissal for Xavi and Ozil said the lack of control is costing him.
“Barcelona has good players in every position, but has had too many injuries this season,” according to an interview with Brand.
“Maybe they should pay a little more attention to themselves and their mistakes and not always complain about the referees. It doesn't help.
“Real Madrid has a fantastic season. I didn't expect it after Karim (Benzema) left the club, but they are doing very well.”
Ozil's career at Real Madrid, from 2010 to 2014, has come to an end Pep Guardiola Dominant period in charge of Barcelona, with the Germany international seeing just two El Clasico wins from 11 before Guardiola's departure in 2012.
