Houston Dynamo are hopeful that the deal to take their defender Geoff Cameron to Stoke City will soon go through.
Stoke have made a firm offer to sign the American international defender, but they have yet to agree a fee.
Major League Soccer own the rights to every player, so Stoke have to negotiate with the league rather than Houston themselves.
Reports in America claim Stoke bid $1million (£650,000) but MLS want closer to $3million (£1.9million) for the 27-year-old.
After talks in England last week, Cameroon returned to the States and even played in their 4-0 win over DC United at the weekend.
"I think (Monday is) a key day in determining whether or not the transfer is going to happen or not," Dynamo president Chris Canetti said in the Houston Chronicle.
"We had a positive weekend where there were good discussions and both sides kind of understood what it's going to take to make a deal happen.
"We will share proposals and see if we can get closer to a deal."
Cameron hopes that the win over DC United was his last for Houston.
"It was a great way to end it here, especially if it was my last game," Cameron said.
"Can't thank the Dynamo fans enough. They were amazing and always are."
