What do you think about this VAR decision?
A controversial penalty was awarded to Olympiacos after Youseff El Arabi was judged to be fouled in the box after VAR consultation in the 4th minute of play.
Frenchman Mathieu Valbuena converted from the spot.
AEL forward Abiola Dauda could have levelled the score in the first half's added time, but his shot brushed the post.
Olympiacos have six points from two matches, while AEL sit in eleventh place on one point.
