Mark McGuinness signed a new deal in South Wales in August 2023, keeping him at Cardiff City until the summer of 2027.

Born in Slough, McGuinness joined the Arsenal Academy at the age of ten and went on to sign his first professional contract with the Gunners in 2019. In August 2020, the central defender was handed a start by Mikel Arteta in Arsenal’s pre-season victory over MK Dons; McGuinness netted an impressive header in a 4-1 win for the Premier League side.

Soon afterwards, McGuinness joined Ipswich Town on a loan deal for the 2020/21 season. The centre-half made his competitive professional debut during a 1-0 win over Gillingham, and went on to feature on 25 occasions for the Tractor Boys throughout the duration of the campaign, scoring once.

The commanding centre half, signed a deal with the Bluebirds in the summer of 2021. He spent the first half of the 2022/23 season out on loan with Sheffield Wednesday, earning huge plaudits for his dominant performances in the heart of defence. Macca was recalled by City for the second half of the campaign and was a mainstay in the Bluebirds' backline for the remainder of the calendar year.
