For a glimpse into the significance of England's showdown with Spain, look no further than Leah Williamson's tireless efforts to regain full fitness. Despite having been sidelined for nearly a month, the Lionesses captain is leaving no stone unturned in her quest to lead her team out at Wembley on Tuesday. Williamson's unwavering dedication is a testament to the magnitude of this encounter, with the winner potentially securing a spot at the World Cup in Brazil.

The Arsenal centre-back has been working diligently behind the scenes, combining private medical sessions with full participation in tactical preparations at St George's Park. Should Williamson not be risked, the door may open for the patient and persevering duo of Lotte Wubben-Moy and Esme Morgan to form a centre-back partnership. Both players have been handed opportunities in recent qualifiers and are now vying for a starting spot alongside Jess Carter, Alex Greenwood, and Maya Le Tissier.

Wubben-Moy, the ultimate squad player, has been fine-tuning her game with the help of her partner Tao Geoghan-Hart, while also maintaining a sense of perspective through her community work. Meanwhile, Morgan's bold decision to join Washington Spirit has paid dividends, with the centre-back developing significantly since her move to the States. As England prepares to face the world's top-ranked nation, the contributions of Wubben-Moy and Morgan could prove pivotal in the pursuit of victory.
