#2 Tottenham Hotspur
Tottenham Hotspur is the second club on this list. Spurs have already had some serious business with Ajax in the past as they have bought Christian Eriksen, Jan Vertonghen and Davinson Sanchez. Toby Alderweireld is another player from Ajax's highly-regarded academy in their squad but the difference there is that he was at other European sides before joining Tottenham.
All these players all play a vital role as part of Tottenham's senior side and as a result, de Jong could continue this trend. Also, he should not have any problems with settling in quickly as his compatriots would help him ease into life in England's top-flight.
Mauricio Pochettino is an exceptional coach, one doing a tremendous job with this Spurs squad. More importantly, he loves to work with young players and that is very important for de Jong - who play a similar attacking style just like Ajax.
