Clasie spent this past season in Belgium on-loan with Club Brugge and is up for sale at St Mary's
"Being abroad hasn't worked for us," he said, referring to his family.
"The transfer amount can indeed be a problem, but perhaps the club (Feyenoord) sells some players."
Clasie has indicated he'll take a pay-cut to help the transfer along.
"I will do everything to be happy again," he added.
