The French attacker feels the Magpies, currently fourth in the table and having just picked up a point at Old Trafford, can challenge at the top if they grow in confidence
"I think if we gain in confidence, we can go and get the title,” he told The Sun.
The Magpies sit fourth in the Premier League table with 26 points, with last week’s 3-1 away defeat to Manchester City their only loss of the season, and have conceded the fewest goals at 12 along with Liverpool and Manchester City.
Meanwhile, summer signings Yohan Cabaye has won a place in the French national team and Demba Ba has scored eight goals, and Ben Arfa – who recently returned from injury problems that kept him out for most of last season – believes there is no reason why the side cannot build on their fine start.
"I think the only thing that makes a difference is the confidence. We really have good footballers here. If we carry on like this, then we can do something," he said.
The Magpies were unlucky to concede a goal after Wayne Rooney’s shot deflected off first Steven Taylor and then Javier Hernandez. However, they were then fortunate to win a penalty, converted by Ba, after Rio Ferdinand appeared to win the ball from Ben Arfa in a sliding challenge.
On the penalty, Ben Arfa give his account of the situation, “What's certain is I received a big blow to my head. I don't know if Rio Ferdinand got the ball but the main thing is we got the goal.”
Goalkeeper Tim Krul made a string of excellent saves to keep Newcastle in the game at 1-1. The pressure exerted by the Red Devils intensified as Jonas Gutierrez was sent off for a second yellow card. However, the champions were unable to find a breakthrough.
Unlike Ben Arfa, manager Alan Pardew stressed that he was not getting carried away with his team's performances or raising expectations.
"We only think about the next game," he said.
