Maldonado spun exiting the Senna S on the second lap, while Senna hit Sebastian Vettel at Turn 4 on Lap 1.
"We had an excellent start moving up several places but unfortunately I lost the rear of the car at Turn 3", said Maldonado.
"It was a slippery surface and there wasn’t much grip which caught us by surprise at the beginning. There wasn’t much we could do so we were unlucky today".
Senna added "I had a good start and was racing well but unfortunately I had an incident when Sebastian tried to take the apex and there was nowhere to go".
"This is racing and sometimes these things happen. I want to take the opportunity to thank the fans who were such a big support at my home Grand Prix as it always makes a big difference".
