Matic clipped the ball across the edge of the box for Valencia on the right-hand side. The right-back, unmarked and under no pressure, unleashed a thumping volley straight into the top corner.
A perfect start for United at Old Trafford with Everton keeper Jordan Pickford unable to respond to such a powerful finish.
