Montero is now in talks with Ecuador's Emelec - with a deal slated to be rubberstamped on Monday.
"We had some talks with (coach Jose) Bordalás, as it is best to leave," confirmed Montero to Ecuadorian radio.
"I came to Spain to play and I could not do it, luckily Getafe is doing very well."
On Emelec, he added: "It seems that some conversations have been leaked. On Monday it will be important so that we can define everything. I've talked with my family and everyone about returning. The president is making a great effort."
