Former Manchester City captain Andy Morrison believes victory at Luton Town will prove decisive in the title race.
City came from behind to win 2-1 and end a run of four Premier League games without a win.
Morrison told City's website: We've been asking for more goals from Jack, we know what he brings to the team and it was a tremendous second half.
The blow right on 47 minutes to go 1-0 down, to show the character second half, tremendous.
It's a big moment for me in the season."
