The Ivory Coast international is in contention to feature against Crystal Palace in Saturday's Premier League opener for the Reds at Old Trafford.
He did not play in our sole pre-season friendly against Aston Villa last weekend, with Tim Fosu-Mensah partnering Harry Maguire in the starting XI.
The 26-year-old was injured last summer but recovered in February to regain a place in the squad, starting with the Premier League victory away to Chelsea.
He played in three further league fixtures - wins over Manchester City and Bournemouth, and the 1-1 draw at Tottenham in our first game of Project Restart.
