Former West Ham United striker Savio Nsereko is being tracked by Interpol after disappearing in Italy.
The Ugandan-born former Germany U20 international, currently with Fiorentina but loaned out to Serie B side Juve Stabia, texted his coach last Thursday to say he would not make training for 'personal reasons'.
He has not turned up in a week and his mother has instructed Interpol to trace him.
Juve Stabia sporting director Salvatore Di Somma said: "The player's mother lodged a complaint with Interpol and the police have released a photo of him to try to find him soon.
"Currently there is still no trace of the player and his family, close friends or police know where he is or what has happen.
"I am sorry above all for the human impact of this affair and naturally hope he can be found as quickly as possible."
