Mario Balotelli, whose wacky antics have filled the British newspapers almost daily in the last two and a half years, is set to return to Italy with AC Milan after a deal was agreed with Manchester City on Tuesday.

The Italy striker, a boyhood Milan fan, first broke through at rivals Inter Milan and is returning home for a fee media reports have put at 20 million euros ($26.92 million) after a largely frustrating spell with the English champions.

"Transfer agreement for Balotelli signed with Manchester City. Medicals tomorrow in Milan, then personal terms until 2017," Milan director Umberto Gandini said on Twitter.

City manager Roberto Mancini, who gave the player his debut at Inter, had said Balotelli would not be leaving in the January transfer window but the striker's desire to go back to Italy appears to have won the day.

Tales of the 22-year-old blowing up his bathroom with fireworks or walking into a school asking for the toilet have amused British fans but City supporters have felt shortchanged after he netted just 20 league goals since his 22 million euro move from Inter.

Going back to Italy will be no walk in the park though for Balotelli, with Milan owner Silvio Berlusconi recently saying his fifth-placed Serie A side did not need a "rotten apple" like the combustible forward.

Berlusconi later apologised.

Controversy also followed Balotelli while at Inter where team mates once assaulted him for wearing Milan colours. He also got into trouble for turning up at a northern Italian prison and asking to look around.
