Milan, Jan 11 (IANS): Former Italian football club Inter Milan's Brazilian midfielder Kerlon on Monday revealed that team-mate Mario Balotelli used to urinate on his colleagues' playing boots.

Kerlon had penned a deal with the Italian Serie A giants in 2008 but he did not make a single appearance for the club and was loaned to teams like Holland's Ajax and Brazil's Parana.

However, he remembers the time he had spent with Balotelli at the club.

"Balotelli is a very nice guy and an extraordinary person, but he did some unbelievable things off the pitch. He had a habit of arriving at training before anyone else and peeing on all the players' boots... it was very funny,” Kerlon was quoted as saying by goal.com.

"I've never seen a kid at 18-years-old do something like it and not feel sorry for any of it, veterans Julio Cesar and Maicon."

The 27-year old Brazilian also said he never dared to do the famous "seal dribble" -dribbling past opponent while balancing the ball on the head - during his time at the Italian club because of the power and height of defenders like Marco Materazzi, Lucio and Walter Samuel who formed a sturdy backline for the outfit back then.

"I did a pre-season with Jose Mourinho at Inter, but I never tried the dribble," Kerlon said.

"The guys were very tall and strong, it's complicated. If Materazzi hit me, I would fly away."
