Thomas Muller scored the only goal of the game, on 63 minutes, to move the Bundesliga leaders 13 points clear of second-placed RB Leipzig, and make it 20 games unbeaten in all competitions, since November last year.
After the game, while Ancelotti admitted his side struggled to find a breakthrough in the first half, they kept pushing, and were ultimately rewarded.
He told the club’s official website: “I’m very pleased with my team’s performance.
With Leipzig having dropped off the pace in recent weeks – the surprise league challengers drawing one and losing two of their last three games – Muller admitted it was “nice” to have such a big lead going into the final stretch of the season.
The striker, who has struggled for goals this term, and netted just he second in the league against Gladbach, explained: “The cushion is very nice. Of course we were aware of the situation, and we absolutely wanted to win the match.
“You saw in the first half we quite hit the gas, and you saw how things can go in football at times.
“We were a bit weaker against Frankfurt last weekend, but we were 2-0 in front at half-time. Today we went full throttle and it was 0-0. That’s why we love football, it’s so volatile.”
Borussia Monchengladbach coach Dieter Hecking, meanwhile, praised his players for their performance despite ultimately succumbing to the Bavarians.
He added: “I’d like to pay my team a huge compliment, we did a fantastic job. Of course the result is disappointing. If you lose 1-0 all the effort didn’t pay off. But my team’s morale and spirit were outstanding once again. The only thing that dampens our mood today is the result.”
