Tottenham, Everton and Newcastle are leading the pursuit to sign Enner Valencia.

The slight striker plays for Mexican Premier Division club Pachuca, where he has enjoyed a prolific spell since moving in January.

Valencia has been excellent for Ecuador in the World Cup.

Pachuca's vice-president Andres Vassi has admitted it will be hard to hold on to the strier if a big offer comes in.

"Enner Valencia's value increases every day. We don't know if he will stay, it will be hard given the offers we have received," he told Mexican ESPN.

"The options that a great player at this level gets are to be taken into account. But for now he has to keep doing things right.

"No doubt it would hurt us to let Enner Valencia go, but we are realistic about his quality."
