Sunderland have announced the signing of Manchester United defenders Paddy McNair and Donald Love for £5.5million.
Numerous reports had suggested a deal for the pair was forthcoming as new Black Cats boss and former Manchester United manager David Moyes sought reinforcements for his first season on Wearside.
And the former Everton boss moved swiftly to acquire the two highly-rated players.
McNair, 21, is a Northern Ireland international and versatile centre-half and can operate at right-back, right wing-back as well as in the middle of the park.
Love, also 21, who was on loan at Wigan Athletic last season, is a right-back, who is also comfortable in midfield.
Both players have signed four-year deals at the club.
Moyes told Sunderland's official website: "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.
"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."
Moyes' first signing was 27-year-old Senegal international centre-back Papy Djilobodji from Chelsea for £8million on a four-year deal.
