"There's always discussions every now and then," he told Sky Sports.
"I'm not going to lie and say no, there's always little discussions and you talk to people and see 'what could you offer' kind of thing but it never went further than that.
"There's always been things in the media and stories being written and that's never the best thing for everyone here back in the factory," he continued.
"If you're working away making a part that's going to be on my car, if you see Norris has links to here or there, it's never probably the best thing to see.
"So for the team's sake I think it's always why we wanted to get it done now just to put those rumours to rest. And that was it. I was convinced this is where I want to stay so as much as there were 'hey, how are you?' kinds of things at other places, it never went further than that, and as soon as I came back here it was a done deal."
