Robben claimed he was in the final stages of securing a new five-year deal with the club despite interest from Real Madrid and Bayern Munich.
Hans Robben, the winger's father and agent, remains confident his son will sign a contract with Chelsea and insists he not spoken with any other club.
Robben senior told Sky Sports News: "At this moment, we are in negotiations with Chelsea and we are trying to make a new deal.
"And, if it doesn't happen, he still has a two-year contract left, so there's no rush and there's no problem.
"You never know in football, but there's a big possibility that he plays for Chelsea next season.
"What I do with negotiations is always just stick to one party. At this moment, it's Chelsea.
"If we don't have a deal, there may be another club, but while he still has two years' contract left I don't see any reason why we should talk to any other club."
