Felipe Massa fears Williams are being left behind after yet another poor show in qualifying.
The Brazilian's miserable weekend, which has included a crash in FP1 and five-place grid penalty, was compounded by both he and team-mate Lance Stroll being knocked out of Q1 – something that is becoming a regular occurence for Williams.
“I was happy with my lap time but the car is not competitive enough,” bemoaned Massa.
“It’s quite disappointing to go out of qualifying in Q1. It shows the main issue on the car is we’re not going forward.
“The others are going forwards, we are going backwards. It is pretty clear that we need to really improve development, we need to improve the pieces we put on the car to make the car better.
"That’s not what’s happening at the moment.”
