Lewis Hamilton said he was disappointed with Nico Hulkenberg after a clash with the German forced him to retire from his final race for McLaren.

Hamilton was leading in Brazil when he was collected by a spinning Hulkenberg as the pair diced for position in challenging conditions in Sao Paulo, with the Briton forced to park his car with damaged suspension.

Hulkenberg was able to continue and despite being handed a drive-through penalty, took the chequered flag in fifth place - with Jenson Button taking advantage of the incident to come through an secure victory.

Speaking to reporters afterwards, Hamilton was unhappy to see his time with McLaren come to an end with a retirement and the Briton admitted he was disappointed that there had been no apology from Hulkenberg after the chequered flag dropped.

"The dude did not even come and say sorry," he said. "That is what happens when you are racing with the less experienced.

"[However] A big congratulation to Jenson and Sebastian. They did a fantastic job. I feel OK. I am happy for the team that we got a win and feeling good for the future. I feel numb, a little bit like I did in 2007, and it is mixed emotions at the moment.

"I'm sad that we were leading and I didn't get to see through the race and also that I am leaving. But I am excited for the future and hopefully I will have a little bit of luck at some stage."
