Atletico Madrid winger Simao is interesting Chelsea boss Luiz Felipe Scolari.
"This is surprise to me," Simao told the Spanish press after learning of the transfer speculation.
"Scolari said nothing to me when I was with Portugal but this is significant as it means the work I have been doing at Atletico is positive."
Reports in Spain have claimed that Atletico have already rejected an offer from Chelsea this summer, with Simao valued at around £20 million.
