Man City signing Castillo: I was Man Utd reject
The striker joined Manchester City on a year-long loan after using his own money to leave Shakhtar Donetsk. However, it is not the 23-year-old's first visit to Manchester.
"I had a trial at United but it didn't come to anything," he said yesterday. "I've still got photos of me with Sir Alex and all of the players. Maybe now I can get my revenge on them with City."
