Arsenal smelling blood.
They drive forward and release Eddie Nketiah for a strike that the visiting keeper saves.
Arsenal have a record of W4, D0, L0 when scoring the opening goal in the UEFA Europa League this season.
Good news for the Gunners.
That goal also pulls the rug from a visiting side that were taking the game to them a bit.
Tierney has not been able to force his way into the side much this season. Takehiro Tomiyasu has the left-back spot right now. But boy did the Scotland international enjoy that.
