Tottenham interim boss Ryan Mason felt the officials on the field and elsewhere dealt his team a cruel hand in the 3-1 defeat to Leeds United.
Goals from Stuart Dallas, Patrick Bamford and Rodrigo gave Marcelo Bielsa's men the points in a pulsating contest at Elland Road – a defeat that all-but ends Spurs' hopes of sneaking into a top-four Premier League spot.
Son Heung-min equalised for the visitors during the first half and Harry Kane thought he had given Spurs the lead, only to be pulled back for offside.
Replays showed the call to be marginal in the extreme, but the video assistant referee delivered bad news for Tottenham, leaving Mason frustrated.
"My first look, my second look and my 10th look tells me it’s not an offside decision," Mason told Sky Sports.
"At 1-1, it's a big moment. In my opinion they got that one wrong. I can't believe it was given offside, to be honest.
"I don't think people understand the momentum shifts decisions like that can have in a game of football."
Despite Opta's expected goals projections from an open game landing 2.49-1.05 in Leeds' favour, Mason also bemoaned missed chances from his team.
"We had opportunities and weren't clinical enough at times," Mason said, Kane having struck the crossbar with a 72nd-minute free-kick when the score was 2-1.
"We had big opportunities and big openings and it wouldn't go in for us, then the last 10 minutes they get one on the counter."
Spurs have three matches remaining this season and trailed fourth-placed Chelsea by five points ahead of Thomas Tuchel's Champions League finalists facing Manchester City later on Saturday.
