Lyon president Jean Michel Aulas has questioned PSG's push to sign Barcelona star Neymar.
The future of the Brazilian remains clouded, with PSG prepared to match the attacker's €222m buyout clause.
Aulas has questioned the strategy, believing the investment would put PSG at financial risk.
He explained: "Neymar? It is not that it irritates me but as an analyst, this investment represents more than €500m over five years.
"And when you try to create a dynamic, you think that it is risky."
