Kubica: Track issues making life harder

Although the circuit was repaired ahead of this morning's practice, the surface kept breaking up in places, meaning the marshals were forced to sweep the debris off some corners ahead of the final qualifying segment.

"It has been a very difficult qualifying with the track which is breaking down in a couple of corners," said Kubica, who qualified in second place behind Lewis Hamilton. "It's easy to make a mistake there so you cannot carry much speed.

"It has not been easy so we are happy with second place. It will be difficult race and if the track is breaking down now then it will be harder. It is very slippery and easy to make mistakes so we have to watch out."

The Pole driver was pleased with his performance after securing his third front row start of the season.

Kubica insisted his team were still not close enough to Ferrari and McLaren to fight for victory, but admitted he will try as hard as possible tomorrow.

"It is very good season for us, but unfortunately the gap is a bit bigger than in the first three races. Here, in Monaco and in Turkey we were a bit off McLaren's and Ferrari's pace," he added.

We have to see what is the strategy tomorrow and also in Q1 and Q2 we were right behind Ferrari and McLaren. It will be difficult race but we try our best."
