Update: Michael Schumacher "conscious" after treatment in Paris

F1 legend Michael Schumacher is conscious after going through a stem-cell treatment in Paris, according to French newspaper La Parisien.

The German was taken into the Georges-Pompidou hospital on Monday, being treated by cardiovascular surgeon Philippe Menasché.

The seven-time Formula One champion hasn't been seen in public since a skiing accident in 2013 where he suffered serious head injuries.

Le Parisien cited an unnamed nurse at the hospital who provided the update on the German.

Schumacher is the sports most successful ever driver winning seven world titles which included 91 Grand Prix victories across an exceptional career.
