Pumas have confirmed the interest of West Ham United and Everton for winger Pablo Barrera.
Pumas have now confirmed that they are considering three offers - from West Ham, Everton and Espanyol - with one bid standing out.
Reports in Mexico claim that the best offer is from the Upton Park club and they are now in pole position to claim his signature.
"We don't want to be making announcements when it's not the correct moment. When everything is OK we will make an announcement," said Pumas director of sport Mario Trejo.
"It's very possible that between Thursday and Friday we will have something more serious to say.
"If there is an important announcement to be made, the president will be in charge of letting everyone know.
"I must admit that after analysing the offers of Espanyol, West Ham and Everton, there is one that has convinced us more than the rest.
"We can't talk too much about it because then everything gets complicated and as we are very near to reaching an agreement we don't want to spoil the negotiations."
