The Argentine made his debut from the bench in the second half and marked the occasion with the equaliser, poking in after good work from Phil Foden with 20 minutes remaining.
Jurgen Klopp’s side ran out 3-1 winners in the end, but Alvarez is looking forward to more hard work to help City challenge on all fronts this campaign.
“Obviously, I’m very happy for scoring my first goal with City, but that stays aside as we wanted to win the trophy,” he said.
“It’s tough, obviously we didn’t want to start this way. We need to keep working.
“It’s going to be a good season to fight for all the trophies and we need to carry on working this way.
“It was a good test to start the season, we played well and played at a good level but we need to keep working to get the results.”
