Liverpool target Javi Martinez admits that he is attracted to the prospect of playing in England.
"I see Premier League matches on the television and the atmosphere is wonderful," he told skysports.com.
"But I don't really know anything [about the interest] as I haven't spoken with anyone.
"My sole mission at the moment is to work hard for Athletic and help the team.
"If an offer does arrive I would look at what is best for two parts, myself and Athletic."
Bilbao have admitted that they are aware of the interest in their prized asset - although they would appear to have few intentions of selling.
"We have not received any formal offers yet," a spokesman said.
"We are calm about the situation."
