Scott McTominay's 86th-minute header gave Manchester United a priceless victory at Aston Villa as they fight for Champions League qualification.
United appeared to be clinging on for a point as Villa created a succession of chances after Douglas Luiz cancelled out Rasmus Hojlund's first-half strike.
But McTominay settled a thrilling contest when he got in front of Matty Cash and rose to meet Diogo Dalot's right-wing cross.
United manager Erik ten Hag punched the air in delight as his side moved to within five points of their hosts, who remain fifth, and six adrift of Tottenham.
