Nico Rosberg in the Barcelona paddock today

Nico Rosberg has confirmed that he will be in the Barcelona paddock today, taking a look at the new cars take to the track for the third day of testing.

The German retired from the sport at the end of last season when he won the drivers championship, his first title after being locked in battle with former team mate Lewis Hamilton for three years.

Rosberg was already in Barcelona this week at a Mercedes sponsor event, but is interested in heading to the circuit to check out the new cars.

He said there: "I might go to the track tomorrow (Wednesday) just to say hi and check it out, as I'm here anyway."
