Sunderland have announced the signing of Manchester United duo Paddy McNair and Donald Love for £5.5 million.
McNair and Love, both 21, have signed four-year deals at the Stadium of Light.
Black Cats boss David Moyes was enthused by the signings and spoke of their long-term potential.
"Paddy is a young, athletic player who is improving all the time," he told the club's official website. "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.
"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."

McNair broke into the United team during the 2014-15 campaign under Louis van Gaal and was part of the Northern Ireland squad at Euro 2016.
Love, a Scotland under-21 international, played in the Premier League and Europa League for United last season and can play at full-back or in midfield.
