McLaren Formula 1 racing director Eric Boullier is unsure whether or not Stoffel Vandoorne will have to take a ༒grid penalty for next weekend's Singapore Grand Prix following his retirement at Monza last Sunda🅺y.

Vandoorne took a 25-place grid penalty for the Italian Grand Prix in a bid to get a fresh poweꦍr unit for Singapore, only to suf൲fer a loss of power mid-race that forced him to park up.

McLaren is targe𝓡ting a return to the points in Singapore given the slow-speed nature of the Marina Bay Street Circuit, but Boullier conceded that the team is not yet sure whether Vandoorne will have to start from the back due to a penalty.

"We are not sure yet whether we will have to change the MGUꦡ-K unit," Boullier said.

"It is repairable. Eve🌃n the engine [in qualifying] was repairable. We just didn’t have enough time before the race because o🍸f parc ferme."

Considering McLaren's chances in Singapore, Bo🐼ullier is expecting the team to fare well as it did in Hungary, where it scored its only double-points finish of the season.

"Singapore should be both cars in Q3 as the t🐟arget," Boul♕lier said.

"I think it is t⛦he second best circuit for us, behind Budapest."
