Why want Beckham?

I can't think why on earth PSG, a club that wants to be one of the biggest clubs in Europe would want Beckham for? I am sure they don't need the publicity and for sure it can't be for his football talent.

Revenue.

why??

come on its kinda obvious dude.,. the french league is really not a big league, PSG is not a big club(it has money and potential but thats all!)- someone like beckham would make psg big in the british, asian,african and us markets- he could even put the french league on the map on his own.
