Beckham signed a five-month contract with PSG in January and has since made eight appearances for the Qatari-owned outfit, including a start in their 2-2 Champions League quarter-final first leg against Barcelona in Paris last week.
"Because in the situation that we are in now, the club has been changing from a normal club to a top club, and Beckham gives you some kind of confidence.
"He has the responsibility, on the pitch and off the pitch, to lead the way for these two months (which) is very important.
"He has a quality, a big quality; he has a touch that I haven't seen many players have. And he is very elegant when he plays."
