European Championship winner Marcos Senna has revealed he would be "interested'' in a January move to Manchester City.
The Spain midfielder, who is under contract at Villarreal until 2010, is believed to be one of the players on City manager Mark Hughes' wishlist as City owners Abu Dhabi United Group prepare to bankroll a spending spree next month.
"I have heard about the big project at City and I'm flattered by their interest,'' Senna was reported saying in the Daily Mail. "The Premier League is a big league and I am interested in the challenge.
"It is complicated leaving Villarreal because I am excited by the season and we are still involved in the league and the Champions League.
"It would take an enormous proposition by City for me to leave but it is not impossible.''
Villarreal sporting director Jose Luis Llanez appeared to open the door for a bid when he added: "We have received no formal offers but in football nothing is impossible.
"If we get a big offer we would consider it.''
