Eriksen, who has now scored in five consecutive matches for his national side, scored the only goal of the game as the red and whites ran out 1-0 victors in Podgorica.
The goal brings his overall total to 17 from 72 international appearances.
“I had the chance and gave the ball a smack. Luckily it went straight in. Maybe [the goalscoring run] will stop at some point, but not at the moment,” the skilful attacker told news agency Ritzau.
The 25-year-old Tottenham star was again one of Denmark's most prominent players as he performed in a similar advanced creative role to that he fulfils for the 2017 English Premier League runners-up.
Eriksen told Ritzau he believes he is playing better than ever.
“I feel very comfortable on the pitch, like I do at club level. I feel I have plenty to give and am confident, and am generally making the correct decisions,” he said.
“It began halfway through last season and I feel I am riding a wave. It will hopefully continue,” he added.
Denmark meet Romania on Sunday in qualifying group E's final round of matches.
A draw will ensure Norwegian coach Åge Hareide's side second place in the group and therefore a probable spot in the play-off round, though the Danes can still qualify automatically for next year's finals in Russia by winning their group, should rivals Poland slip up at home to the Montenegrins.
