Houston Dynamo insist Cameron talks continuing with Stoke
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."
