George Saville and Paddy McNair helped Northern Ireland get their Euro 2020 qualifying campaign off to a good start with a 2-0 win at home to Estonia.
The Boro pair started in midfield for Michael O'Neill's men, and it was Niall McGinn and Steven Davis who scored the decisive goals.
McNair came close to breaking the deadlock on 18 minutes when he met a Jordan Jones cross at the back post, but he couldn't take advantage from close range.
The hosts took the lead when McGinn lashed home before Davis tucked away a penalty 15 minutes from time after Saville was brought down inside the box.
