Red Bull insists it has no plans to sell Toro Rosso.
The energy drinks company is pushing for the 2010 title with its main team Red Bull Racing, while its second team is a midfield runner at best.
"It is and remains our rookie team," Red Bull mogul and Austrian billionaire Dietrich Mateschitz told Der Spiegel newspaper.
"We run our best young talents with this Formula One team," he added.
According to Mark Jenkins, a business strategy professor at Cranfield University in the UK, Red Bull should drop Faenza based Toro Rosso.
"It doesn't make any sense with the current regulations for Red Bull to own two teams," he is quoted by Bloomberg.
But the report also said Red Bull has confirmed it has no "concrete" plans to sell Toro Rosso.
The media research monitor Margaux Matrix found that, with its four Red Bull-branded F1 cars, Red Bull has got almost 267 minutes of TV airtime so far in 2010, compared with 52 minutes for Ferrari.
