Napoli coach Rafa Benitez has refused to comment on progress of talks over Manchester United midfielder Marouane Fellaini's move.
There have been reports of Napoli pulling out of negotiations.
"We need to continue to work with these players and see if we can do something at the end or whether we will continue improving what we have," Benitez insisted.
"Fellaini? He has a contract with Manchester United, so at the moment I'm thinking about improving our players."
