Hamilton-Rosberg rivalry is good for the team: Wolff
Lewis Hamilton and Nico Rosberg are preparing for the Monaco Grand Prix with a sense of "anger" - something that excites Mercedes' head of motorsport Toto Wolff.
The battle between the Silver Arrows team-mates is a fascinating one born of the desire to become F1 world champion.
Hamilton pipped Rosberg to the crown last year and has started his title defence strongly, winning three of the first five races.
Rosberg hit back by winning in Spain last time out and is looking to close the gap further with a third straight win on the streets of Monte Carlo.
Hamilton edged proceedings on Thursday by topping the timesheet in both practice sessions and Wolff believes an exciting weekend lies ahead.
"The rivalry has always been intense on track and we've seen it from the start of the day," he said.
"They were both out there in anger, pretty competitive lap times straight from the beginning.
"And it's good for the team because it pushes the team - it pushes the two to new levels, competing against each other."
Hamilton has finished second to Rosberg in the principality for the past two years and spoke about his dream of achieving a "perfect weekend" off the back of his new deal with Mercedes.
