UNAM Pumas have hinted that West Ham United are winning the race to sign winger Pablo Barrera.
Everton and Espanyol are also being linked with the 23-year-old who made three substitute appearances for Mexico during this summer's World Cup in South Africa.
Reports in Mexico claim that the best offer is from the Hammers, although the Pumas' director of sport Mario Trejo is refusing to confirm any deal just yet.
He said:"We don't want to be making announcements when it's not the correct moment. When everything is OK we will make an announcement. 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."Subscribe to Football FanCast News Headlines by Email
