Who plays Niamh in Ted Lasso season 4?

Aisling Sharkey plays Niamh in Ted Lasso season 4. Niamh is a defender on Richmond's women's team and the twin sister of fellow defender Siobhan.

Sharkey was announced as one of the new season 4 cast members alongside Tanya Reynolds, Jude Mack, Faye Marsay, Rex Hayes, Abbie Hern, and Grant Feely. Her character is part of the expanded women's-team storyline.

The distinction between Niamh and Siobhan is important because the two characters are twins but are played by different performers. Sharkey plays Niamh, while Rex Hayes plays Siobhan.

Niamh's position is also different from several other new players. Gemma, played by Abbie Hern, is a striker, while Lizzie, played by Faye Marsay, is a centre-back. Jude Mack plays Boots, the team's goalkeeper.
