Chelsea striker Philipp Prosenik has left Stamford Bridge for the San Siro after the Blues agreed an undisclosed fee for his sale with AC Milan.

Prosenik moved to west London during the summer of 2009 from Rapid Vienna when he was only 16, but failed to make a first-team appearance for Chelsea.

The Blues were reported to have beaten a number of top European clubs to his signature almost three years ago but, it would appear, Prosenik failed to make an impression at Chelsea.

Milan have been keeping a close eye on his situation, and now Massimiliano Allegri has pounced to bring the 18-year-old to Serie A.

"Philipp Prosenik's contract has been deposited with the Lega Serie A," read a statement from the Italian giants, according to Sky Sports.

With Prosenik leaving Stamford Bridge, Chelsea have moved to add another youngster to their ranks by completing the signing of 20-year-old midfielder Kevin de Bruyne from Genk.

The Belgian youngster will complete the rest of the season with Genk, before moving to London in the summer.
