Jenson Button has warned that Sergio Perez is "too aggressive" and says he's not the only one who feels that way while the Mexican says his team-mate was just as bad.
McLaren team principal Martin Whitmarsh endured several nervous moments on the pitwall at the Bahrain Grand Prix as his two drivers went head-to-head on a number of occasions.
The duo made contact at least once and a part of Perez's front-wing endplate went flying off the car on lap 30, but the Mexican ended up finishing P6 with Button claiming one point after being forced to make a fourth stop late in the race.
Button, though, wasn't happy with his team-mate after the race, telling Sky Sports that the 23-year-old is "too aggressive".
"I was very vocal on the radio, emotions were running high, but I would say exactly the same again," he said.
"The racing was great out there. The only person that wasn't was Checo [Perez].
"He was too aggressive, I would say. At 300 km/h, you don't expect your team-mate to come alongside you and bang wheels with you. It was a bit of a surprise, and I'm probably not the only one that feels like that."
Perez, meanwhile, admits he took his aggression too far, but believes Button was also a bit naughty.
"I was as aggressive as he was with me," he said. It was probably, too much. It's something we have to speak about."
