The 24-year-old has been signed on loan from Standard Liege for the rest of the season as Celtic look for defensive cover.
Kelvin Wilson begins his two-game suspension this weekend and Gershon has insisted he is ready to make a name for himself in Glasgow.
He said: "I must prove myself because it is only six months. I think that it is clear the team will need a defender and I am here to help. It is normal that you need a lot of players.
"It is a jump for me from where I was. Celtic is one of the biggest clubs in the world and is very famous in my country. To be a successful player here would be a dream for me.
"I can only say that I am a team player. I like to help the players around me and I give everything on the pitch.
"I like to win. I am a real winner.
"If you see the games I have played and talk to the people who know me, they will tell you that you can see that clearly when I am on the pitch."
Gershon was able to get to know his team-mates in the relatively informal environment of Celtic's Marbella training camp last week, but there was already one familiar face in the squad. Fellow countryman, Beram Kayal, was there to show him the ropes and Gershon believes that has made the transition easier.
"I have known Beram for a long time as we played together for the national team and the under-21 team," he told Celtic TV.
"For any player it is always easier if there is someone there that you already know.
"But training was good.Everyone was friendly and the atmosphere in the team is very good."
Meanwhile, Celtic chief executive Peter Lawwell has applauded the Celtic support after briefs for the club's forthcoming Uefa Champions League tie against Juventus were sold out yesterday.
Lennon's side face up to the Italian giants on February 12 and demand for gold-dust for the last -16 clash is such that the club could have sold double the amount of tickets they had available.
"Once again our supporters have demonstrated their incredible backing for the club," he told the club website.
"With the level of demand we've had, Celtic Park could have been full for the visit of Juventus with a capacity of over 100,000.
"Sadly, this means many will be disappointed today, but crucially we know that every Celtic season-ticket holder will have been able to get a ticket for another memorable European night."
