The entire Hibernian bench were adamant a Legia player was in an offside position prior to the penalty award, but neither the fourth official or the referee were having any of it.

That half sums up Aberdeen for a while now. Some really good play without enough shots on target, before conceding an avoidable goal.
Daniel Birligea's neat finish is the difference, which came after Jack Milne and Gavin Molloy did not cover themselves in glory when dealing with a long ball.
The good news is they have a second half against 10 men to come after Juri Cisotti was sent off for taking down Nicolas Milanovic.
Double save for Hibs - one from Jordan Smith and one from Rocky Bushiri!
Pawel Wszolek has his shot from the edge of the box palmed away by Smith. It comes back to Vahan Bichakhchyan, and his shot is headed away, on the ground, by Bushiri.
But did the Hibs defender actually use his arm to block it? The referee is checking with VAR.

Josh Mulligan's late strike resuscitated Hibernian's hopes of progressing to the Conference League as they emerged from the first leg of their play-off with Legia Warsaw at Easter Road trailing 2-1.
For much of this game, it looked like David Gray's side's European adventure had run its course as they put in a tired-looking performance and found themselves two goals down.
Rocky Bushiri's first-half handball resulted in a penalty that Jean-Pierre Nsame smashed high into the net, before Pawel Wszolek added a second on the stroke of half-time.
And in a moment that could prove pivotal, Legia had a third ruled out in the second-half after a lengthy VAR intervention. Bartosz Kapustka had tucked home what looked to be a tie-ender, but Wszolek was offside earlier in the build-up.
That lifeline buoyed Hibs and swung momentum back in their favour for the first time since the opening 10 minutes.
Mulligan was the beneficiary, getting onto a cross at the back post and reacting quickest when his initial shot was blocked to poke it under the keeper.
It could have easily gone another way, as Legia spurned a few golden chances to wrap the game up at 3-0.
Vahan Bichakhchyan missed the best of them, as he skied over from the back post when he was completely unmarked. Nsame missed another.
But Hibs were also guilty of missing a couple of sitters. Bushiri headed over and Thibault Klidje glanced wide from one of a series of Chris Cadden deliveries.
Come the end of the game in Warsaw, Hibs could still come to rue those chances but at the moment, Mulligan has given hope to his side.
Hibs analysis: No excuse for tired legs after rotation
The line-up against Livingston in the Premier Sports Cup on Sunday was the first time David Gray had rolled the dice and rested some of his European XI.
Those who missed out all came back in, but a tiredness haunted the starters at Easter Road as they struggled to get their second wind after a fast start.
The opening of the game was very physical, with Josh Campbell and Kieron Bowie wearing sore ones early on. It took the wind out of Hibs' sails and allowed Legia to get a foothold.
Hibs' haven't found themselves behind too often in recent times, but the experience of coming back against Partizan must have been in their minds as they grew in confidence towards the end of the game.
There were plenty of chances missed, so they go to Warsaw knowing they can cause problems for Legia, but they must be far more clinical if they are to make it to the group stage of a European competition for the very first time.
Reaction to Hibs' defeat on the Scottish Football Podcast
Hibernian head coach David Gray: "This tie is very much still alive. We've already said to the players that we went to Midtjylland, we went to Partizan, and had huge performances and results. We're going to need to do that again.
"It's big moments in the game. To goal just before half time was a poor goal. You can talk about the penalty but we're not going to do that. We can't affect that now.
"Clearly the one that's the factual one on the offside was a big moment in the game. If that goes 3-0, it's a very different night.
"I thought we had really good, clear-cut chances and should have done better with them. But I've just reminded the players that we've gone toe-to-toe with a team that went to the quarter-finals of the competition last season."
What's next for Hibernian?
Hibs exercised their right to postpone this weekend's Premiership game with Falkirk, giving them more time to recover for the second leg of this clash.
That takes place next Thursday at Stadion Wojska Polskiego (20:00 BST).
