Besic joined the Blades on deadline in August 2019, arriving on a season-long loan from Everton.
Capped 40 times by Bosnia Herzegovina, Besic will add mobility, energy, versatility and Premier League experience to United's midfield ranks, with the 26 year-old impressing Chris Wilder and his management team whilst on-loan at Middlesbrough for much of the Blades time in the Sky Bet Championship.
Besic lists Hamburger SV and Ferencvaros amongst his former clubs, prior to moving to Goodison Park.
