"You can feel it, from the first moment here," said Sabitzer, when asked about the positive spirit within the squad.
"Leeds away is a big game and we have to win those games. We were ready for it, the attitude was good.
"We knew before [Leeds at home] they would be two tough games and we had to be focused right until the end."
"He [Marcus] is a great guy, a great player and he's helping us a lot at the moment," acknowledged the Austrian, when asked about his prolific team-mate.
Sabitzer was also asked by reporters at Elland Road about his relationship with Erik ten Hag, the manager who brought him on transfer-deadline day to bolster the Reds' midfield ranks for the business end of the season.
"He's good, he's talking to me a lot about what he's expecting from me, so I'll try to fulfil that," replied Marcel. "I'm feeling good and I'm liking it here so far."
Inevitably, the question came up as to whether the midfielder could extend his stay beyond the current campaign.
"It's a loan and that's all I can say [about that] at the moment," he said. "What I can say is I'm feeling very good here, I like the team, I like the club, I like the atmosphere at Old Trafford... so we will see what happens in the summer."
The win over Leeds United temporarily took the Reds into second place in the Premier League, until Manchester City beat Aston Villa later in the day to reclaim the position directly behind leaders Arsenal.
"It's hard [to win the title], we are a bit behind them but, as I said, we'll keep going and doing our job," said Sabitzer.
"There are big games ahead so we have to keep going and keep the energy high and then we will see what happens at the end of the season."
