David Moyes has completed a £5.5million double swoop for defenders Paddy McNair and Donald Love from Manchester United.
The 21-year-olds have both put pen to paper on four-year deals and take Sunderland’s number of summer signings to three.
Moyes said: “Paddy is a young, athletic player who is improving all the time. He has experience for Northern Ireland and we want to bring as many international players to the club as we can. Donald comes highly recommended and is another young player who I hope can develop and improve here.”
He added: “I want to add some young players to the squad as well as some senior players and both of them have got really good potential and the opportunity to improve.
“I want to bring in players who are here for the long term as well as the short and hopefully these two are here for the long term.”
Central defender McNair heads for Wearside having played his part in Northern Ireland’s successful Euro 2016 finals campaign after breaking into the first team at Old Trafford, while Scotland Under-21 international full-back Love, who can also play in midfield, tasted both Premier League and Europa League action with United last season.
