England manager Gareth Southgate announced his squad on Thursday for the games away in Malta on September 1 and at Wembley against Slovakia on September 4.
The full squad for the two games was confirmed by the team's official Twitter feed:
The 24-year-old made his debut against Arsenal and then scored his first goal for the Foxes against Brighton, and the Telegraph's Matt Law feels some of the Premier League's bigger clubs may regret not signing him this summer:
Chalobah is the other surprise inclusion, and he was also on the move this summer, swapping Chelsea for Watford, which Goal's Nizaar Kinsella feels may have helped his international hopes:
Southgate has said part of the reason he opted to include Maguire and Chalobah was due to the pair's displays at the UEFA Under-21 Championship in Poland, per Henry Winter at the Times:
The only other uncapped player to be called up is Jordan Pickford, who is included following his summer move to Everton. He is one of four goalkeepers in the squad.
Southgate has gone for eight forwards, including Danny Welbeck and Daniel Sturridge, while Jermain Defoe also retains his place.
The England boss has named a 28-man squad for the two games, although this could be due to injury concerns over some players, per Matt Law at the Telegraph:
Meanwhile, there is no room in the squad for Ryan Sessegnon—who had been tipped for a call-up after being left out of the youth sides—Fraser Forster, Chris Smalling or Theo Walcott.
The England captaincy is also yet to be decided with Southgate saying he is in no rush to make a decision on who will wear the armband on a permanent basis, per Winter:
It is a large and youthful squad selected by Southgate with the focus clearly on the future. The England boss appears keen to see a number of young players in action as he aims to guide his side to next summer's FIFA World Cup finals in Russia.
The game against bottom of the group, Malta, may give Southgate the chance to see some of the younger members of his squad in action, although a stronger team could be picked for the visit of Slovakia, who sit second in the group, two points behind the Three Lions.
