Bojan has joined Milan on a season-long loan.
"My relationship with Roma was weird from the beginning. I didn't get to play much. I didn't reach an agreement with Roma, and then Milan offered me the opportunity to play. It's an honour for me to be here.
"I am here at Milan to stay. I want to do well here and help the team. I am here for a year, but I want to stay after my loan deal expires next summer.
"It has been incredible for me since day one. The players here have really given me a great welcoming."
