Starting his first Premier League match in four months, the centre-back was welcomed with open arms by United fans, who loved his high-risk, high-reward pirouette turn to shrug off Mohamed Salah in the first half.

United held out at Old Trafford to win 2-1 and go five points clear of top-four rivals Liverpool in second place with eight Premier League games to play.
