You might as well say he can't play as striker either as a substantial amount of time he played there he failed.
you're linking psg to martial on the basis of it being a rich french club, despite no interest being shown by any of the parties, including us, for a deal, and its not random?
how can psg offer him first team football? their attacking first team players are better than Martial. Aubameyang at least could displace Cavani, unless you believe Martial on the back of last seasons performances could/would do the same. That also goes for him trying to displace Moura , Di Maria, Draxler.
