The Brazilian bagged two goals in the recent 3-3 draw.
The Brazilian has been highly disappointing since his big money move from Hoffenheim in the summer, with him failing to adapt to life in the Premier League.
There have been some decent performances though, with impressive displays in big wins over Chelsea and Manchester City previously.
“I hope I can play like that against all teams, not only the big teams,” he told Liverpoolfc.com.
“Obviously it’s good to play well against the good teams but my aim here is to help the team by scoring goals and doing whatever I can on the pitch.”
“There was extra motivation against Arsenal. I’m sad that we couldn’t win the game but I’m happy that I could help the team by scoring two goals and at least we got a draw in the end.”
Liverpool could do with the Brazilian upping his game in the second half of the campaign as well, having struggled up front so far this season.
They have scored fewer goals than relegation threated Sunderland so far, with Christian Benteke failing to prove his worth and Daniel Sturridge once again struggling to maintain his fitness.
There is a chance for Firmino to impress and make the role his own in the second half of the campaign, and Jurgen Klopp will be hoping that will be the case.
