Uwe Rosler has criticised the refereeing during Leeds' 3-0 defeat at Middlesbrough.
Leeds were swept aside by Boro, who opened the scoring inside the first two minutes thanks to a David Nugent goal, before Giuseppe Bellusci comically headed the ball into his own net to make it 2-0.
A slip from Sol Bamba late on then allowed Diego Fabbrini to round Marco Silvestri and turn the ball home, capping off a comfortable victory for Aitor Karanka's men.
However, Rosler has pointed to two major refereeing decisions which hampered his side. Firstly, striker Mirco Antenucci had a goal ruled out for offside at 2-0, though replays suggested that the Italian was level with the last defender, and the goal should have stood.
Additionally, Rosler told LUTV that he believes Boro forward Christian Stuani should have been sent off, but was allowed to get away with fouls even though he was on a yellow card.
"The major decisions today went against us," said Rosler. "It's disappointing, because the linesman asked for help from the referee to make this call, and I think it shouldn't be like that. The linesman should be 110% sure that our players is offside, obviously he wasnt."
"The decision went against us with Stuani. [He committed] a number of fouls against Charlie Taylor. He was already on a yellow, he fouled him again, when our player was running in to the box, and he shouldn't have been on the pitch. The decisive moments went against us, and that's the story of the game," he added.
However, Rosler did have more positive words to say about winger Botaka. The 22-year-old wide man joined Leeds from Dutch side Excelsior on deadline day earlier this month, and was handed his first appearance for the club - and Rosler was impressed with his hour-long display at the Riverside Stadium.
"I think Jordan Botaka had a decent debut," Rosler stated. "He forced George Friend, who is one of the most attacking wing backs in our league, to stay back. It was his first taste of English football and I think he had a good performance; something to build on."
"I saw that he is getting physically ready for the Championship, I saw today that he is a player who can take us forward on the pitch, who is looking for one-on-one situations, who can open up gaps for us, and also commit defenders. That was encouraging, and I'm looking forward to the next weeks and months to work with him," Rosler continued.
