NEWCASTLE Jets midfielder Ruben Zadkovich was last week given permission to hold talks with Millwall, the Australian side have revealed.
Zadkovic was given time off by his club following international duty with the Socceroos in the East Asian Cup and travelled to England to meet with Lions boss Steve Lomas.
But the Jets insist they have received no formal bid for the 27-year-old, who has previously played for QPR, Notts County and Derby County during his career.
Chief executive Robbie Middleby said: "Ruben was scheduled to have a week off following his commitments with the Socceroos.
"He asked for the opportunity to take up Millwall's offer of a visit during this time and we have accommodated that request.
"At this stage, we have not received a formal offer for Ruben and he remains a Jets player. Ruben is our captain and a highly valued member of our squad and our preference is for him to stay.
"We're looking forward to having him back in Newcastle for pre-season training this week."
