Felipe Massa has brushed off his crash in first free practice for Monaco Grand Prix as simply a 'mistake', but admits Williams are struggling to again find form around the street venue.

A year on from Williams suffering a torrid weekend around the Principality as it struggled with poor grip, though the team says it has worked hard to improve the car's performance on low speed circuits, 14th and 16th for Valtteri Bottas and Massa respectively suggested the gains are minimal.

Hampered furthered by Massa losing much of FP1 when he crashed heavily at Ste Devote, though the Brazilian shrugged off the accident itself, he says the average pace of the FW38 is of more immediate concern.

"It was definitely not a very good Friday," he continued. "We had a crash in the first session which in Monaco can happen, especially when trying to find the limit of the track and the car, a dirty track. The guys did a fantastic job to put the car back on the track.

"When we see we are 14th and 16th, it is not really positive and we need to understand how to make the car quicker here and how to make the car better on slow corners, get better traction. We are struggling a bit."
