Brescia president Gino Corioni admits he still regrets selling Marek Hamsik to Napoli.
Hamsik moved to Napoli in 2007 for €5.5. million.
"I regret letting Hamsik go to Napoli for such a low price," Corioni told Radio CRC on Wednesday afternoon.
Hamsik was rumoured to be a 30m target for Milan this summer, but the attacking midfielder will remain at the San Paolo.
"He's made the right decision in staying at Napoli because that club want to construct a great side," the Brescia chief added.
"Hamsik is not a top champion, but he is still irreplaceable. Players with his characteristics should not be sold."
