Ferrari team principal Frederic Vasseur shot down questions over the problem which affected the team’s cars during the Spanish Grand Prix.

Lewis Hamilton described his car as feeling “the worst it has ever been” after slipping to sixth place in the last race.

Ahead of this weekend’s race Hamilton said both cars had been “massively” compromised by the problem. However he refused to elaborate on the cause, saying Ferrari “don’t want us to talk about it much”.

Vasseur also refused to address the problem when asked during yesterday’s press conference. “When I’m telling you in the press conference that I won’t disclose, don’t come back 10 minutes later to try to understand,” he said.

“And the Friday after, to try to understand, I won’t disclose what’s happened. It is like it is. Full stop.”

Pressed for any details on the problem, Vasseur replied sarcastically: “We put the front wheel [on] the rear.”

Charles Leclerc, who finished third in Spain, indicated at the end of the race he understood the problem the team encountered. “I know why the last part of the race was poor,” he said. “I’ll explain, but there is an explanation.”
