The 28-year-old Cameroon international played a starring role in his side's 4-1 friendly victory over Celtic on Thursday night in front of an appreciative Toon Army on his home debut.
Geremi headed for Tyneside after a four-year spell at Chelsea which brought him several honours, but not regular football.
He will run out against Italian aristocrats Juventus on Sunday relishing the chance to stake his claim for a place in Sam Allardyce's team, and desperate to help the Magpies end their 38-year wait for a trophy.
Geremi said: "At Chelsea, I was not playing regularly, that's why I decided to leave. I hope I am going to play regularly here for what is a big team.
"Newcastle is a big club and it is a big challenge for me.
"This team has gone 38 years without winning anything and we hope with the addition of the new signings, we can try to get there."
The former Real Madrid player, who spent a season on loan at Middlesbrough earlier in his career, lined up in central midfield against the Bhoys and could figure there once the Premier League campaign gets under way.
Scott Parker's £7million move to West Ham, coupled with Kieron Dyer's seemingly imminent departure and injuries to Joey Barton, Nicky Butt, Emre and Damien Duff, has left Sam Allardyce searching for reinforcements in the middle of the park as well as at the back.
However, Geremi, who played as a right winger at the Riverside Stadium and mainly as a right-back at Stamford Bridge, is keen to line up in the midfield.
He said: "I am a midfield player. On Thursday night I played in midfield and really enjoyed it and I hope I will play there most of the time.
"But I am a footballer and if we have a problem in some position and the manager asks me to play there, I will help the team."
Geremi became Allardyce's fourth summer signing as he followed Mark Viduka, Joey Barton and David Rozehnal to St James' Park, and he admitted he was quickly persuaded by Allardyce's ambition.
He said: "I spoke with the manager and he has a lot of ambition, the new owner has a lot of ambition, so I think this team deserves something.
"That's why straight away I gave my full commitment to this team."
Allardyce's efforts to add to his summer recruits are ongoing with injuries once again leaving a Newcastle manager short of bodies.
However, Geremi is already excited at the prospect of playing with the likes of Michael Owen, Obafemi Martins and Viduka.
He said: "We need good players to realise our ambition.
"All players love to play with great players, so I am looking forward to playing with them."
