We cannot win on merit at the moment, says Berger.

BMW Motorsport director Gerhard Berger has attempted to play down Williams' chances this year of winning a Grand Prix after Juan Pablo Montoya came so close in Brazil.

The former F1 driver said: "There are two ways of winning: by your own merit, or when your rivals drop out. If Ferrari or McLaren have problems, we're capable of winning now, but in terms of pure force we'll have to wait until 2002. At Imola we just want to stay as close as possible to the Ferrari's and McLaren's then we'll see what happens."

The Austrian added: "Juan Pablo is gifted with superb car control and raw natural talent, but he has to learn that you can't do everything with talent alone. He's got to develop a cooler, more analytical attitude so that he can help improve his car's performance throughout a grand prix weekend."

"Despite his superb performance in Brazil, he's still learning how to drive in traffic and how to set up his car. But it's only his fourth grand prix. If he gets everything focussed, he'll become a great driver."

On Ralf Schumacher Berger noted: "Ralf's driving performances are very, very close to those we're used to seeing from Michael (Schumacher). I really believe that if they were driving equally matched cars Michael would have to push himself to the limit to stay ahead of his brother. Ralf lacks nothing to go just as fast as Michael."
