Toto Wolff on Red Bull: 'I expect more to come from these guys tomorrow'

Mercedes' Team Principal Toto Wolff came out after the second free practise session of today with more confidence after Max Verstappen ran away with the Styrian Grand Prix last week.

Speaking to Sky Sports, Wolff explained how he was "carefully optimistic" after today's action was complete, but still acknowledged that there is more to come from their Championship rivals, Red Bull.

He went on to add and confirm that changes will be made to the Mercedes car ahead of the British Grand Prix, stating that "there is one big development coming on the car in Silverstone, but it's been down the sleeve for a long time."

He also explained how there is still room to look into how to improve but it doesn't necessarily mean that these changes will be made.
