Marcus Rashford has doubled Manchester United’s lead just before half time finishing off a deadly counter attack.
On one end, Ivan Perisic had a chace to put things level but his strike was saved by De Gea.
And moments later, United had the ball in the back of the net.
One long ball from the back put Rashford through who eased past Eric Dier before firing in an unstoppable strike.
But it was poor defending from Dier who should have done more to force Rashford wider.
