Fernando Alonso on Thursday rubbished claims he fell out with Ferrari's technical director Pat Fry in India last weekend as an "invention".
La Stampa newspaper had reported the row, also involving team boss Stefano Domenicali, lasted until 1am after qualifying, in which the Spanish driver was persuaded not to post on Twitter a complaint about a lack of development progress.
"A nice invention from someone in the Italian media," Alonso said in Abu Dhabi, when asked about the report.
Alonso said it is no secret Ferrari is struggling to close the gap on his championship rival Sebastian Vettel, but insisted the team is "very united".
"We know and it's a fact that we are slower than Red Bull -- we all agree, me, the team, our fans, everyone knows.
"We are very united in our efforts to fix this situation," he added.
