During the 2013–14 season AFC Ajax will participate in the Dutch Eredivisie, the KNVB Cup, and the UEFA Champions League.The first training took place on Monday 24 June 2012. The traditional AFC Ajax Open Day was held on Wednesday 25 July 2013, followed by a testimonial match on 3 July 2013 for the retired former Ajax forward Sjaak Swart also known as "Mr. Ajax" for his 75th birthday.
The 2013–14 AFC Ajax season marks the Jupiler League debut of the AFC Ajax reserves' squad Jong Ajax. Previously playing in the Beloften Eredivisie (a separate league for reserve teams, not included in the Dutch professional or amateur league structure) players were allowed to move around freely between the reserve team and the first first team during the course of the season. This will no longer be the case as Jong Ajax will register and field a separate squad from that of Ajax first team whose home matches will be played at Sportpark De Toekomst while playing in the Eerste Divisie, except for the occasional match in the Amsterdam Arena. The only period in which players will be able to move between squads will be during the transfer windows. Furthermore the team is not eligible for promotion to the Eredivisie. Jong Ajax are joined in the Eerste Divisie by Jong Twente and Jong PSV, reserve teams who have also moved from the Beloften Eredivisie to the Eerste Divisie.
The first training for the 2013–14 season was held on 24 June 2013. In preparation for the new season Ajax organized a training stage in De Lutte, Netherlands. The squad from manager Frank de Boer stayed there from 15 June 2013 to 24 June 2013. During this training stage friendly matches were played against SDC Putten. The club then traveled to Stubaital, Austria for additional training. The squad stayed there from 1 July 2013 to 9 July 2013. A further friendly match was played against Dynamo Dresden in Germany. Returning to the Netherlands, further friendly matches were scheduled against RKC Waalwijk and De Graafschap on the same day, as well as Osasuna and Werder Bremen on the same day, a few days later.
