Burnley boss Sean Dyche has questioned the decisions to award Olympiacos a penalty and send Ben Gibson off in his side's 3-1 loss in the Europa League on Thursday.
The Clarets were all square at half time at the Georgios Karaiskakis Stadium as Kostas Fortounis's opening goal was cancelled out by Chris Wood's 33rd-minute penalty.
However, the Greek giants regained the lead shortly after half time through an Andreas Bouchalakis header, before Gibson was given a second yellow card for a handball which also led to a spot kick for the hosts.
"I've got to be careful, as usual, what I say. But for the life of me, I don't understand why he has booked Ben Gibson [again]," Dyche told the official Burnley website.
"The first one maybe but the second one he has gone to block a shot and it's hit his hip, it's hit his hand. How can that be deemed deliberate handball? It's just an impossibility.
"Then he gives him the yellow card and it's probably the world record for how quickly he got it out of his pocket, and then gets Ben Gibson sent off.
"Then, [for] the whole game, we're having to hold on to make sure we preserve what it is at that time and take our away goal back."
The return leg takes place at Turf Moor next Thursday night, with Burnley able to reach the group stages with a 2-0 win or force extra time with a 3-1 victory.
