Castillo reveals Bolton interest
Xabi Castillo has issued a come-and-get-me plea to Celtic - despite being linked with Bolton.
The Real Sociedad left-back, 23, is out of contract at the end of the season and is keen to move overseas.
Because he is under 24, a Spanish club would have to pay £2million to secure his services.
"I have interest from Italy, from Bolton in England and Greece," Castillo said in the Daily Mail.
"But what I want most of all is a proposal from Celtic.
"I wanted to make some money for Real before I left but, in football, things do not always work out as you like."
