Barcelona contributes to the celebrations of the Catalan National Day, which are held this weekend. There will also be a dedicated mosaic on the stands before the game which is played at 4PM CET.
Barcelona will wear the red/yellow-striped Senyera KitFC Barcelona will play the La Liga home game against Athletic Club in the red/yellow 'Senyera' Shirt, for the first time.
The Barcelona 2013-14 Away Shirt was inspired by the colors of the 'Senyera', the Catalan flag, and comes with red and yellow stripes. The shorts and socks of the Barcelona 13-14 Away Kit are red.
In the 2013-2014 season, the Barça 13-14 Away Kit proved ill-fated for the club as they failed to win in the first couple of matches with the red and yellow shirt. The first loss of that season was also recorded in the Away Shirt, interestingly against Saturday's opponents Athletic.
The Barcelona 'Senyera' Shirt will not become the official Third choice for the 2014-15 season though, as the new light green Barcelona 2014-2015 Third Kit is set to be unveiled shortly.
