Wolves were given a boost after 28 minutes when Olympiacos were reduced to 10 men. The visitors broke quickly and, as Diogo Jota darted towards the box, he was taken out by Semedo.

Nine minutes into the second half El Arabi scored before Wolves levelled after 67 minutes through Neto's 25-yard low drive.
