Lyon president Jean-Michel Aulas has described the world record capture of Neymar from Barcelona as a big boost to the French Ligue and congratulated Paris Saint-Germain counterpart Nasser al-Khelaifi on the feat.
Aulas was however quick to question the 'real cost' of bringing Neymar to France, beyond the €222 transfer fee.
The Lyon boss, owner since 1987, had been one of the critics of the deal and even described the pursuit of the player as a "risky" venture capable of harming the French economy.
On Thursday, he posted a congratulatory message on Twitter even though it carried a subtle caveat:
"Congratulations to Nasser for the realization of this worldwide unique operation," he wrote.
"I'm impatient to know about the real costs of the operation."
Despite his reservations, Aulas later said Neymar's switch to the French capital would be an "immense" boost to the profile of Ligue 1.
Lyon finished fourth in France's top tier last term after ending the two previous seasons as runners-up to PSG.
