Ferrari confirmed reports its technical boss James Allison is staying put at Maranello.
In the days before the Italian grand prix, Ferrari media insider Leo Turrini claimed that contrary to mid-season speculation, Briton Allison recently signed a new deal through 2018.
Team boss Maurizio Arrivabene confirmed: "I already confirmed that in Belgium. Yeah, he’s got a long-term contract with us."
Allison, 47, joined Ferrari from Lotus in mid 2013.
Ferrari and its oil partner Shell are also staying together, having announced a further five-year contract extension.
"Signing this contract is a further step forward in terms of stability," said Arrivabene.
