Lotus drivers Romain Grosjean and Pastor Maldonado were left to rue separate collisions at at the Rettifilo chicane which put them out of the race at the Italian Grand Prix.
Both drivers started inside the top 10 but Grosjean made contact with Felipe Nasr while Maldonado and Nico Hulkenberg collided, leaving the Venezuelan on the side lines for the eighth time this season.
"We had the potential of a good race ahead of us," said Grosjean.
"I made a strong start but got hit by a car from behind in turn one which broke my rear suspension so that was it for us. It was a too optimistic move from Nasr who hit me which meant my race was over."
"I had contact in Turn 1 where the Force India came into the side of me and took out my front-right suspension and that was the end of my race," rued Maldonado.
"We were looking for a strong finish and we had potential for that."
