Now a Wales international after her senior bow in October 2021, Cain was previously capped for the Lionesses at Under-17s, Under-19s and Under-21s level, and also represented Wales at youth level.
Although limited by injury for the early months of her maiden season at the Club, Cain made her debut for the Foxes in a 3-2 victory over Blackburn Rovers just before Christmas.
Her quality and importance to the team, meanwhile, was further demonstrated with her first goal in Leicester's colours, sealing a 1-0 win over Crystal Palace at Farley Way Stadium in February 2021.
Cain signed a contract extension in July 2021, along with eight other first team players, to continue her Foxes journey in the Barclays FA Women's Super League, but an ACL injury ruled her out for the remainder of the 2021/22 season after five appearances.
