Long time Brazilian Grand Prix race leader Nico Hulkenberg admitted he is disappointed to miss out on a podium.
Hulkenberg led the McLaren of Lewis Hamilton before making a mistake and spinning.
The German then collided with Hamilton when he attempted to re-pass him, with a penalty dropping him to fifth.
"That was a lot of fun - very entertaining and there was so much happening all the time! We had a great chance to finish on the podium today, but it slipped away, which is a shame", he said.
"In the early laps it was difficult to keep the car on the track in the very damp conditions, but it was not really wet enough for intermediates and I stuck with the slicks. It was the right decision and soon I was leading the race. I felt comfortable but eventually I made a small mistake and Lewis got ahead of me".
"I managed to stay with him and was fighting to get the lead back when we touched. It’s hard to say what happened but I was making a move going into turn one and had a slightly loose rear. I was about to turn in and suddenly there was contact. It’s a shame for both of us because we were having a great battle. I managed to keep going but I had lost a lot of time. Fifth place is still a super result to end the season and I think the team did an excellent job this weekend. I hope they enjoyed the race – it’s a nice leaving present in my last race".
Team mate Paul di Resta caused a late race safety car when he hit the wall at the final corner.
"It was a very tricky race and not easy to make the calls with the weather constantly changing. Ultimately we made the wrong decision to switch to the intermediates in the early stages because the track began to dry quite soon after my stop. The tyres lost performance quickly and I went back to the slicks just before the safety car came out. That brought us back into play, but I struggled for grip at the restart and lost a few places. When we went back to the intermediates in the closing stages we were more competitive and I was up in eighth place. Unfortunately with a lap to go I aquaplaned in the final corner. It was a big hit with the wall, but I’m OK".
