With a number of European clubs including the Premier League side interested in the centre-back, his representative insists he will not move until the summer
The defender's representative, Ted Philipakos, has revealed to Goal.com that his client will not move during the winter transfer window despite interest from several European teams.
"George continues to attract interest from Europe - most notably from England and Greece, to this point - but I do not expect George to move in the winter period," Philipakos told Goal.com.
"George feels good about the fact that we have options," he explained. "If he wants to extend with MLS, we're in a stronger position now than ever before to make a deal that truly reflects his value, at least in the context of the MLS market, while if he wants to move to Europe, he’ll be able to do that in 2012."
With John's current MLS contract due to expire at the end of the 2012 season, Philipakos is confident that the 24-year-old will receive further offers in the coming months.
"I think we could see someone make a bid this summer, but if George wants to go to Europe he can just play out his contract and move as a free player next winter," he said.
Last summer, Premier League side Blackburn had a reported bid of £1 million accepted for John, yet the two parties were unable to agree personal terms.
John since has entertained the possibility of pro-longing his contract after Dallas were eliminated from the MLS playoffs last month, and Philipakos revealed that after two years of putting contract negotiations on hold, he is set to resume conversations with MLS and FC Dallas about an extension.
"MLS and FC Dallas have approached us about a new contract at various points over the last two years, most recently this summer, and at that point we asked to put the issue on hold until the offseason. I believe we'll be talking more this month," he added.
As previously reported by media outlets, John turned down opportunities to train with Aston Villa and two Greek clubs, instead Philipakos says that his client will be resting and working out on his own.
"Unless something changes, he'll start preseason with FC Dallas on January 15."
