Michael Schumacher believes his Mercedes team compromised his car set-up too much for Brazilian Grand Prix qualifying in the hope that it rains on Sunday.
The German, in his final race before retiring from Formula 1, qualified down in 14th position with a car set-up aimed at taking full benefit of race day's predicted rain.
With qualifying being mostly dry, however, Schumacher struggled for pace and was knocked out in Q2.
"For obvious reasons, I am not particularly happy about the qualifying session today," said Schumacher. "We might have compromised the car too much for the rain which is expected for tomorrow and was also forecast for qualifying.
"When the drops came down just before, it looked even more likely. Anyway, my starting position is now quite tricky, and I will have to see what we can make out of it tomorrow.
"Of course, coming from where I am does not make it easy, but I will definitely try to fight my way up the field."
Team-mate Nico Rosberg also had a wet-weather set-up, but managed to qualify in 10th position and reckons he can have a stronger performance on Sunday.
"To progress into Q3 and the top 10 in qualifying today was a reasonable achievement for us," he said. "Our car set-up was a little compromised due to the race conditions expected tomorrow so we should be in better shape then.
"You can't change anything after qualifying so I hope we are well prepared and that we have chance to score some good points tomorrow."
