Lewis Hamilton has refuted suggestions by his current team boss that he is regretting his decision to sign with Mercedes.
A long-time protégé of McLaren and then a F1 driver with the team for six years, Hamilton is leaving Woking at the end of this season to head to Brackley in a three-year deal.
However, since announcing the swap, Mercedes have not scored a single World Championship point and languish down in fifth place in the Constructors' Championship.
This prompted McLaren team boss Martin Whitmarsh to say he thinks Hamilton "on occasions" regrets the decision to change teams.
The Brit, though, says this is not true.
"I was a little bit surprised to hear that," Hamilton said when asked about Whitmarsh's comments. "It's clearly not the case.
"But I've got a great team and I've been with them a long time.
"I'm sure everyone has emotions within the team, but I'm still here giving 100 percent to them for the last two races.
"Of course it's quite emotional for me but I'm very, very happy with my decision."
Joined by the title contenders, Sebastian Vettel and Fernando Alonso, for Thursday's press conference in Austin, Hamilton was asked for his thoughts on missing out.
"It is what it is. I'm happy just to be here fighting in the last two races for my team," the 2008 World Champ said.
"I just want to do the best job. We can still fight them, even though we are not fighting for the Championship.
As for the Championship duo, the 27-year-old reckons they are dealing with the pressure remarkably well.
"It's amazing to see how much focus they have considering how much pressure is on - they are both World Champions and they both handle it without a problem."
