Both Schumacher and Hamilton have won seven world championships, the most in F1 history, but 2016 champion Nico Rosberg recently suggested that Verstappen's achievements put him right up there as one of the best of all time.
Verstappen compares with Schumacher and Hamilton
Now, Berger has gone one better by suggesting that even the likes of Schumacher, Hamilton and the supremely talented Ayrton Senna do not come close to Verstappen's current level.
“Max didn't make a mistake last season," the Austrian told AutoMotorSport.
"At least that happened to Senna every now and then. At the time, Senna and Schumacher benefited from racing karts from an early age and doing nothing else in life other than racing. This applies to all drivers today.
"But Verstappen still drives virtual races on the simulator in his free time. Sometimes three a day. So he is always busy with this topic. He thinks through where you can overtake and where you can't. Neither Senna, Schumacher nor Hamilton had this tool.
"It's just noticeable that Max is always in the right place. At the start, in the first corner, in a duel. I can't think of anything that could be done better than him. That's why Max Verstappen is probably the best we've ever seen in Formula 1.”
