Marko sees volatile Perez: 'Just up and down with him'

Red Bull advisor Helmut Marko has summed up Sergio Perez 's Grand Prix weekend at the Hungaroring in the Red Bull in his column for Speedweek. The Mexican put his RB20 into the wall during qualifying on Saturday, but drove a strong race on Sunday. After the Belgian Grand Prix, Red Bull will decide on Perez's future.

"A typical GP weekend from Perez, I would say. Unpredictable, very good on Friday, just behind Verstappen and with the best longruns of all the drivers. Then unfortunately a silly mistake in qualifying, which resulted in the 16th starting position, followed by a very strong race, finishing in seventh place," Marko wrote of the Red Bull driver's weekend.

The Austrian from Graz sees that it is off and on with the Guadalajara-based driver. "It is just up and down with him, nobody knows when he is going to shine or when he is going to make a mistake, there are just no constant good performances," the 81-year-old explained in his column. Marko sees that becoming first in the constructors' World Cup standings will be a tough job.

"Defending the drivers' title will certainly be less difficult than defending the constructors' title. As McLaren continues to score points with both drivers in front, that is our biggest problem, that we have scored far too few points in the last few races with Checo Perez," the Red Bull man concluded.
