The origins of Shaw's connection with Santos trace back to roughly May 2017. Early public whispers began circulating when the pair were spotted together at music festivals, including London's Wireless Festival, alongside mutual acquaintances. Unlike high-profile celebrity romances that start with coordinated Instagram launches, Shaw and Santos let their relationship develop far away from red carpets.
By late 2017, Santos became a fixture in the players' lounge at Old Trafford. Shaw had just navigated some of the hardest chapters of his playing career, including a grueling recovery from a double leg break suffered in 2015 and public scrutiny over his fitness under former United manager José Mourinho. Santos offered a stabilizing presence during that tumultuous period, giving Shaw an anchor away from the tactical demands of Carrington.
