Schumi Jr takes centre stage

Oschersleben - Michael Schumacher's manager Sabine Kehm urged "restraint" on Wednesday as the record Formula One champion's 16-year-old son Mick began testing ahead of his car-race debut later this month.

While seven-time F1 champion Schumacher continues his recovery from injuries suffered in a ski accident in December 2013, son Mick began his first public test session before a large media presence in Oschersleben.

Mick Schumacher is set to make his car-racing debut in the ADAC Formula 4 series beginning on April 25-26 in Oschersleben in Lower-Saxony state.
