Tottenham Hotspur will have 10 players competing at this summer’s World Cup in the United States, Canada and Mexico. That figure could increase if Marcos Senesi, who will join Spurs on a four-year deal when his contract with Bournemouth expires at the end of June, is a late addition to Argentina’s squad following an injury to Leonardo Balerdi. Spurs have also made two offers for Brighton’s Jan Paul van Hecke but are yet to agree a fee for the defender, who is part of the Netherlands squad for the tournament.Some of Tottenham’s players are due to face each other during the competition. Pedro Porro and Rodrigo Bentancur could feature for Spain and Uruguay respectively in an exciting climax to Group H on June 27.There are lots of other Spurs storylines to keep an eye on. The Athletic has picked out the best ones.A taste of Robertson’s leadershipSpurs confirmed the signing of Andy Robertson last week but he will not officially join them until his contract with Liverpool expires at the end of this month. For the next few weeks, the defender will be focused on captaining Scotland at their first World Cup since 1998.Robertson only started 11 games in the Premier League last season but he is crucial to Scotland. The 32-year-old started all of their qualifying games and assisted Scott McTominay’s late winner against Belarus.(Ian MacNicol/Getty Images)One of the reasons Spurs signed Robertson, and initially tried to make the deal happen in January, is his leadership skills. The left-back has already given a good example of that before a ball has even been kicked in this tournament. He wrote a letter and gave a gift to every single member of Scotland’s squad before their opening game against Haiti.Robertson also has the perfect opportunity to show Spurs fans that he is still a quality player in group stage games against Morocco and Brazil, in which he will relish the challenge of battling with Real Madrid’s Brahim Diaz and Barcelona winger Raphinha respectively.A proper look at VuskovicThe secret is out when it comes to Luka Vuskovic. The centre-back scored six goals in 28 appearances for Hamburg last season, including towering headers and clever backheel flicks. He has also shown an aptitude for crunching tackles and elegantly dribbling his way out of trouble.The teenager held his own against Harry Kane in a 2-2 draw with Bayern Munich earlier this year and will be reunited with the former Spurs striker in Croatia’s opening game against England. Vuskovic will be teaming up with ex-Spurs midfielder Luka Modric to bring England down in a repeat of the 2018 World Cup semi-final.This tournament will be the biggest test yet of Vuskovic’s ability. He has started four of Croatia’s last five games in all competitions, including their warm-up friendly against Belgium at the beginning of June. Spurs want to sign Van Hecke but head coach Roberto De Zerbi would find it difficult to ignore and overlook Vuskovic if he excels for Croatia.(Miguel J. Rodriguez Carrillo/Getty Images)Danso vs MessiAustria are making their first appearance at a World Cup in 28 years and they face the daunting prospect of taking on the holders Argentina in their second group game. Kevin Danso is not guaranteed to start at centre-back because head coach Ralf Rangnick alternates between him, captain David Alaba and Phillip Lienhart. If Danso is named on the bench, he can still expect to be involved at some point in Austria’s efforts to limit the influence of Lionel Messi.
