Cardiff City have made rookie Arsenal defender Mark McGuiness their second summer signing.
The Republic of Ireland Under-21 international spent last season on loan at Ipswich Town.
Cardiff boss Mick McCarthy has already added senior Republic international striker James Collins to his squad following his departure from Luton.
McGuiness failed to make a senior appearance for Arsenal, but was a regular for their youth sides, having first signed as a 10-year-old.
He has won four Under 21 caps for his country, including an appearance against Wales in Wrexham in March 2021 where he came up against Cardiff City youngster - and current Wales Euro 2020 squad member - Rubin Colwill.
