Lukaku, Pogba... and Martial executed perfectly into the top corner
The Red Devils doubled their lead with a brilliant effort from Martial, who swept the ball beyond Butland's reach in spectacular fashion.
Stoke City had pushed forward since Valencia's opener, but United are clinical, and Martial eventually doubled the lead for the hosts.
Lukaku held the ball up brilliantly on the left flank and the Belgian shifted it back for Pogba, who spotted his compatriot Martial at the top of the box. The finish from the striker was superb.
