We have the breakthrough - and it has gone he way of the hosts!
I have no idea how Xavi Simons has managed to score there, but he has taken his chance brilliantly to give PSV the lead just before half-time.
Simons dribbles past three or four Arsenal players before slotting past Aaron Ramsdale.
Big finish to the half please, lads.
Despite Arsenal dominating possession, both sides have managed one shot on target so far.
The PSV fans are in fine voice as the half-time break approaches.
Manchester United's players are in the house.
