Sunderland AFC have signed Paddy McNair and Donald Love from Manchester United for a fee of £5.5m ($7.12m). The defensive duo, both 21, have signed four-year deals at the Stadium of Light.

Newly-appointed Sunderland boss David Moyes said he was looking forward to working with McNair and Love, saying they both have "really good potential".

"Paddy is a young, athletic player who is improving all the time," the former United manager explained to the official Sunderland 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."

Moyes signed the duo from his former club United and admitted he is keen to sign more young players who can help Sunderland progress. "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," he said.

"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."

In addition to McNair and Love, Sunderland have also been linked with a loan move for fellow United youngster Adnan Januzaj, who does not reportedly feature in Jose Mourinho's plans for this season.
