The Red Devils now have the giant 25-year-old center back under wraps through the 2021/22 season.
Bailly is nearing full fitness after his latest injury setback, knee and ankle injuries costing him dozens of matches since arriving from Villarreal in 2016. He underwent knee surgery in late July.

There’s little reason for United not to pick up the option, as Bailly could’ve left for free in the summer and the extension allows for a possible transfer fee.
That said, Bailly has been very good with healthy and in-form, especially in an exceptional debut season at Old Trafford. He has 34 caps for the Ivory Coast, and is nearing the prime age for a center back.
United visits Liverpool at 11:30 a.m. ET Sunday, and Bailly is not expected to play.Follow @NicholasMendola
