According to Fichajes.net Alessio Cerci has decided to leave Atletico Madrid.

He is not being played by Simeone and Mancini likes the player. He fits perfectly into the role on the wing that Mancini’s new formation at Inter would necessitate. Atletico’s former Nerazzurri head coach has given Inter the go ahead to initiate a January transfer for the Italian winger. A move would require some assurance for repaying the €16 million spent on the ex-Torino winger last summer. Inter would have to move quickly because Simeone recently spoke on the fact that alongside Inter, Manchester United and Arsenal are also interested in the player.
