Beckham is not expecting any favours and - with his debut still likely to be a couple of weeks away - does not expect to go straight into the starting XI when he is fit.
"We'll see, I don't know (where he will play). I can either play in the middle or on the right," he said. "Goalkeeping's not my biggest strength so I'll stay out of the way of that one. I don't expect to come in to this team and to be a starter in the teamsheet. I've never expected that wherever I have gone. I'll work hard for my place, I'll work hard to make the team successful."
Beckham had been training with Premier League side Arsenal in order to try and fast-track his fitness before he is due to meet up with his new team-mates in Paris next week.
"It's going to take me a couple of weeks at least to get up to speed with the rest of the team," he said. "But I think, I've always kept myself pretty fit. I needed time after last season to kind of recover, because after the Achilles injury that I had.
"It took a while for me to get going with that, but I have taken time off, I've trained with Arsenal a couple of days, and once I get in with the team I don't think it's going to take me long to be up to speed. I want to get playing as soon as possible to be honest."
