Locked in a battle for this year's World Championship, things appear to be getting even more heated between Mercedes' Lewis Hamilton and Ferrari's Sebastian Vettel.
After a dominant victory in Spa last weekend, which saw Vettel cut Hamilton's championship lead to 17, Hamilton was left needing to clarify comments he made regarding Ferrari's "tricks".
Despite the Brit insisting he wasn't questioning the legality of the Ferrari car, Vettel stated he's "not so sure" and seemed unconvinced when asked about his rival's comments.
“I think he said in the press conference something with tricks, but I think he said many times he doesn’t want it to be interpreted in the wrong way,” Vettel said.
“I think maybe it did, so I am not quite so sure.”
The German did, however, stress that he's maintaining his focus ahead of Ferrari's home race in Monza and the continuation of the championship battle.
“For all of us, in terms of is the car is legal or not, the FIA is responsible for it and we have several checks throughout the weekend to prove that,” Vettel said.
“So as long as I don’t hear anything from that front then I think it’s fine, same for the others.
“As I said, maybe it’s more of a question for him, and for us it’s to keep our head down.
“If there’s something like momentum then to use that momentum to make sure we go forward.”
And after Ferrari's dominance at Spa, Mercedes boss Toto Wolff admitted his team have "many deficits" to the rival constructor.
This has certainly pleased Vettel who, after years of Mercedes dominance, admitted his joy at Ferrari's progress.
“I think people forget that for the last five years Mercedes has been absolutely dominant, especially in terms of power unit,” Vettel said.
“Obviously it’s nice for them to put us in that position, as it means they believe they’re not the strongest anymore, so it’s good to be up there with them and be a match.
“I don’t think we can take anything for granted. I don’t think we are anywhere near the place they have been for the last years.
“We have to work hard to make things happen and we are determined to work hard this weekend to put ourselves hopefully in the same position again that we have a great pace in the weekend, especially on the race on Sunday.”
Formula One continues this weekend in Monza, with Vettel looking to close the gap to Hamilton even further, in front of Ferrari's home crowd.
