I don't know any details but there's been a thread on red cafe for quite a while with quotes from him in 2009 talking about having agreed a deal with us but the idea being for him to carry on learning in Chile for a few more years. I'd presume that's when we came to the arrangement. Then there are quotes from about March this year from his club directors talking about us 'robbing' the the club and how it would be a bad move for him. I guess he's improved quite a bit and there may have been a hint from other clubs they'd come in and pay a higher price so we've rushed our option a bit.
