Ralf Schumacher believes that his son, David, and the son of his brother Michael, Mick, need more time to develop as drivers and as people before they are to make an impact within Formula 1, despite Mick already having joined Ferrari's driver academy.
The grand prix winner has joined the Sky Deutschland team as the German broadcaster returns to the paddock.
However, Schumacher - whose brother Michael is the most successful driver of all time - will not be in the paddock, but will rather report from a Munich studio.
Now 43, Ralf said working in F1 again was "an easy decision".
But in the not too distant future, there may be Schumachers back on the actual grid.
One of them is Mick, Michael's son who is in Formula 2 this year. The other is David, Ralf's 17-year-old son.
"Mick and David still need time," Ralf told Kolner Express newspaper.
"Mick is on the right track with his European F3 title and he has also completed a good Formula 2 test, but he is also a rookie," he said.
"And after a year of driving a Formula 4 car, David is going to Formula 3 for the first time -- that's where he needs to do his homework," Schumacher added.
Mick will continue his development with Prema Racing in 2019, but is now affiliated with Ferrari as a junior driver.
