Monk is not expecting Villarreal midfielder De Guzman to return to the Liberty Stadium.
"We talked to him earlier in the summer, he wanted to keep his options open and I guess his options still are," said Monk.
"I do not anticipate him coming back at this moment in time.
"With the high turnover of players we have had, and trying to get as much information across to them as possible, we have not got time to wait around.
"I am not closing the door on it, if it happens it happens, but he and his agent were the ones who decided to keep his options open and we can't wait about."
