Asked in her pre-match press conference if Williamson will start Tuesday's UEFA Women's Euro qualifier against Ireland, England boss Wiegman confirmed as much.
"I think what Leah brings is, of course, vision, in possession she's just very bright and finds the right pass, and the flexibility, the defence, being able to defend the space behind her together with everyone else, because defending doesn't just start with one player, it starts with the team," she said. "That's what I hope Leah will bring to the team tomorrow."
Asked if it will be an emotional occasion for her, Williamson said: "It will be. It was emotional on Friday for me. I'm an emotional person. We've all seen me cry on many occasions. But yes, it was emotional Friday even, because if there's a team that you want to be in in the world, I think the Lionesses would be up there. I just love playing for England."
