Ron Vlaar's agent has told the Mirror that now is the time for the reported Manchester United and Arsenal target to make "a nice big move in his career."
Aston Villa centre-back Vlaar, 29, was linked with a transfer away from Aston Villa in the summer after an impressive World Cup with Netherlands but ultimately remained with the Premier League side.
However, club sources told ESPN FC in October that Villa are holding out for 12 million pounds from United for Vlaar ahead of a possible January deal.
Vlaar's agent, Arnold Oosterveer, has suggested the defender should take his opportunity and secure a move to a team that matches his ambitions.
Oosterveer said: "It is obvious that for Ron, now is the moment to make a nice big move in his career. Ron is very ambitious.
"The situation is ideal for Ron right now. You can imagine that we are not in a hurry. I don't want to react to the rumour that he will move to either Arsenal or Man United, but Ron is very ambitious."
Vlaar signed for Villa from for Feyenoord in 2012 and has since made 66 Premier League appearances for the Midlands club.
