The 21-year-old defender joins Saints having spent the majority of his youth career at Chelsea.

In the final year of his contract at Stamford Bridge, Sam had a successful loan season at Barrow in League 2, making over 30 appearances for the Bluebirds.

Sam played at various youth levels for Northern Ireland and gained a full international cap for his country in 2021 in a friendly against Ukraine.

Speaking to SaintsTV, Sam spoke of how delighted he was to sign for St Johnstone:

“I’m so happy to be here and get the deal over the line. I first heard about a potential move around a week or so ago and I was immediately interested in coming here. I’m really looking forward to getting started.

“The manager was the first to make contact with me and I liked what I heard, he made it a really easy sell for me.

“It’s a brilliant opportunity to come up to Scotland. There’s a real spotlight with so many big games in the Premiership that I’m looking forward to already. I’m here to improve myself but also try be a part of successful St Johnstone team.

“I like defending but I also feel I’m comfortable on the ball as well. I’m here to defend, keep clean sheets and get wins for the team.”
