AC Milan striker Mario Balotelli used to urinate in his Inter Milan team-mates’ boots before training, his ex-team-mate Kerlon Moura Souza revealed.

The 25 year-old Italian born star became known for his bizarre behaviour on and off the field during his time in the Premier League.

Former Inter midfielder Kerlon who played alongside Balotelli at the San Siro in 2008 and 2010 made the hilarious claim during an interview with ESPN Brazil.

"Balotelli is a very nice guy and an extraordinary person, but he did some unbelievable things off the pitch," Kerlon said.

"He had a habit of arriving at training before anyone else and peeing on all the players' shoes".

In 2015, on his return to AC Milan Balotelli was handed a strict set of rules to live by one which was to get rid of his extravagant hair styles.

The controversial striker received a call up for the upcoming Coppa Italia quarter-final against Carpi.

He has been on the sidelines for more than three months with injuries.
