The former Liverpool striker is backing the Italian to score more goals for Brendan Rodgers' side.
Balotelli came off the bench against Spurs to score an 83rd-minute winner, his first in the league since his summer move, ending his long goal drought for the club.
The win also moved Liverpool a point behind the North London side and three points off third-placed Southampton, with as many as six teams now all fighting for the highly coveted Champions League places.
Now, Rush is hoping that the Italian can build upon that goal and continue to score more in the future.
“He’s been patient, Brendan has played him at the right times so I’m pleased for him to get the winner,” said Rush.
“Even after he scored the goal he was running around and closing down and he seemed to have an extra spring in his step. Hopefully that’s the start of many more to come from him.”
Rush was also full of praise for Tottenham as they twice came back from behind against Brendan Rodgers' side only to lose out to Balotelli’s late winner.
The former forward thinks that they should be praised for going to Anfield and looking to win rather than just take a point, while he also says the result blows the race for the Champions League places wide open, whereas defeat for the Reds would have made it hard to finish in the top four.
“I thought it was a great football match and you have to give Tottenham credit as well because they tried to win the game,” Rush added.
“A lot of teams come to Anfield and try and get a draw but Tottenham went for it. If we hadn’t won that game, I wouldn’t say that it’d be impossible, I’d say that it would be very difficult, to get into the top four. Now having won the game it’s all on. There are three or four teams in it.”
