Born December 2, 1994, Donald joined Sunderland in August 2016 when he penned a four-year contract on Wearside.
A tenacious right-back, Love joined Manchester United in July 2002, aged seven.
Hailing from Rochdale, Love, 22, can play in the heart of defence and is also accomplished in defensive midfield.
Having been capped at Scotland under-21 level, the full-back gained his first taste of first-team action when he was loaned to Championship club Wigan Athletic.
Following his return to Old Trafford, Love then made his first-team debut for Manchester United in a 2-1 defeat against Sunderland at the Stadium of Light in February 2016.
Love marked his first start for United a week later as he featured in their 2-1 Europa League defeat at Midtjylland.
Love joined Sunderland with former United team-mate Paddy McNair, and in his first season on Wearside made 18 appearances.
