All our thoughts are with his father Michael and his family at this sad time. ?
Psychologists were also there to provide support to the family.
Portuguese media reports said the teenager had been riding on an uneven piece of land in Troia, near the Ballack family home, when the bike rolled backwards and fell on top of him.
Emilio was born in 2002 to Michael's then-girlfriend Simone Lambe.
The former Germany captain has two more sons from his relationship with Lambe, born in 2001 and 2005.
