Is Rosberg right about 'unprofessional' Verstappen? Horner responds!

Nico Rosberg called Max Verstappen unprofessional ahead of the Hungarian Grand Prix. According to the 2016 world champion, it is disappointing that the Dutchman was sim racing until 03:00 a.m. last night when he was due to race in Hungary the next day. Christian Horner believes conclusions are being drawn too quickly.
