The aftermath of Sunday's Grand Prix continues for Red Bull as its 'team orders' row escalates.
Mark Webber was closing in on teammate Vettel in the final stages of the race, but was apparently instructed not to overtake.
Boss Christian Horner had already been under great stress over the weekend as controversial technical rules were introduced mid-season and yesterday admitted he was surprised by Webber's decision to ignore his instructions on Sunday.
Horner appeared worn out as he attempted to deal with the press who were targeting Red Bull over their team orders.
He said "This is something we have to discuss in private, behind closed doors... at the end of the day, the team is the biggest thing - and no individual is bigger than the team."
Webber has admitted he was furious and had disobeyed orders on Sunday.
