Matthew Stuart Cash (born 7 August 1997) is a professional footballer who plays as a right-back for Premier League club Aston Villa and the Poland national team.

Cash started his career at Wycombe Wanderers and later the FAB Academy before he signed his first professional contract with Nottingham Forest and then established himself as a regular at right back.

Cash had joined FAB after Wycombe Wanderers released him, due to financial problems forcing their youth teams to be disbanded, aged fourteen.

[17] During the season, Forest manager Sabri Lamouchi began to utilise Cash as a right back, after injuries to Tendayi Darikwa and later Carl Jenkinson.

[18] He made the right-back position his own, and his impressive performances led to the Poland national team reportedly monitoring his progress ahead of a potential call-up.

[27] On 26 February 2022, Cash scored a long-range effort in an away victory over Brighton & Hove Albion which was nominated for Premier League Goal of the Month.

He received a yellow card for his celebration of the goal, in which Cash lifted his shirt to reveal a message of support for Poland teammate Tomasz Kędziora and his family, who were in Kyiv during the 2022 Russian invasion of Ukraine.

[37][38] On 1 November, Cash received his first call-up to the Poland national football team for their 2022 FIFA World Cup qualification matches against Andorra and Hungary.

[43] Cash grew up in Iver, Buckinghamshire, working in a branch of the department store Daniel prior to joining the Nottingham Forest academy.
