Mark McGuinness has become the third youngster to leave Arsenal today by signing a permanent deal with Cardiff City.
After Trae Coyle and Zech Medley departed earlier in the day, McGuinness has secured a move to the Championship.
McGuinness has enhanced his reputation significantly in the past year. The tall centre-back scored with a header for the first-team in a friendly against MK Dons last year and then went on loan to Ipswich Town, for whom he played 25 times.
The Republic of Ireland youth international joined Arsenal as a schoolboy before signing scholarship terms in 2017.
Having had some difficult moments at first, being left out of the squad on many occasions and struggling with injury, McGuinness went on to be part of the Arsenal U18 side that won the southern section title in 2019.
McGuinness only played six times for Arsenal U23s but has developed well of late and is now looking to take his game to the next level.
The departure of McGuinness may come as something of a surprise, but it is extremely difficult for centre-backs to make the breakthrough in any case, especially at Arsenal where there are a host of players in that position.
