Siem de Jong is Ajax’s new captain. Frank de Boer made the announcement on Wednesday after SC Veendam-Ajax (1-5). The 23 year old midfielder takes over the band from Jan Vertonghen, who left last weekend for Tottenham Hotspur. Theo Janssen and Vurnon Anita will take over the captainship in De Jong’s absence. Both midfielders are reserve captains.
