Pablo Hernandez has scored six goals this season
Kemar Roofe and Pablo Hernandez scored the goals as Leeds United eased past 10-man Bristol City.
But Robins head coach Lee Johnson insisted the Yorkshire side were "lucky" - and that the game swung on visiting midfielder Josh Brownhill's red card for two bookable offences on 55 minutes, when the score was still 0-0.
"They got away with it," said Johnson after his side's fourth straight defeat. "We were the side who looked like we were going on to win the game until the red card,
"The referee took the easy decision in front of a big crowd. The referee wants to run the show these days.
"There were decisions that we didn't get but I don't care about the refs because they do it to us every week. We have had some poor refs the last few weeks."
Leeds manager Marcelo Bielsa said: "It's a point of view that we have to respect. But we virtually didn't concede any chances for our opponent.
"As far as I know I don't remember anything of note that they created. It was a very comfortable debut for our goalkeeper.
"When I see the game again I will take this into account this point of view that we didn't deserve the result.
"That we played with one player more made it easy for us. But that wasn't the only reason we won. We created plenty of chances."
The game was evenly balanced before Brownhill, booked on 20 minutes for a foul on Ezgjan Aliosk, was sent off for a poor challenge on Roofe.
Leeds took charge thereafter and Roofe gave them the lead from close range for his eighth of the campaign.
The hosts, beaten 4-1 by West Bromwich Albion in their final outing before the international break, added some late gloss to the scoreline when Samu Saiz played Hernandez in with a well-weighted pass and the Spaniard finished neatly.
Leeds, without their two senior keepers Jamal Blackman and Bailey Peacock-Farrell, handed a debut to youngster Will Huffer, as well as Finnish defender Aapo Halme.
But they ended up cruising to a ninth league win of the campaign, which took them up to second for a couple of hours before Middlesbrough beat Brentford in the later kick-off, and ultimately the margin could have been greater but for some wasteful finishing from Jack Harrison and Ezgjan Alioski.
Bielsa's side now face struggling Reading on Tuesday, while Bristol City will hope to end their losing run the following night when they travel to bottom-of-the-table Ipswich.
