Ferrari team principal Mattia Binotto has called for more clarification after Red Bull drivers Max Verstappen and Sergio Perez escaped penalisation at the Monaco Grand Prix. Sunday’s race was a chaotic, wet affair, with the Ferraris of Charles Leclerc and Carlos Sainz Jr. starting on the front row ahead of the Red Bull duo. But a tactical blunder from the Scuderia allowed Perez to take the lead in the race, which he eventually won, during a round of pit-stops, with Sainz coming home second and Verstappen third. However, after the chequered flag Ferrari lodged a complaint to the FIA after footage showed that Verstappen did not keep his car fully to the right of the pit-lane exit line when emerging from his stop ahead of Leclerc, seemingly breaking the rules. But the race stewards decided not to penalise either driver, with their ruling stating that as neither car went across the line, they had not breached the regulations. But this explanation did not go down well with Binotto, who told Gazzetta dello Sport : ‘I would also like to ask the FIA for some clarification. ‘Verstappen crossing the yellow line is quite evident. When this has happened in the past, a five-second penalty was awarded. ‘We don’t understand the passivity shown today. ’ Had five-second penalties been awarded, Ferrari would have claimed a 1-2 around the famous street circuit, and Sainz would have picked up his maiden Formula 1 win. But instead, it was Perez who took victory, with Verstappen extending his championship lead to nine points over Leclerc who was extremely angry with the result, berating his team for costing him victory at his home race . ‘Leclerc’s disappointment is also our disappointment,’ Binotto added.

Charles is right. If a driver finishes fourth something didn’t work out. ‘We did something wrong, on at least a couple of occasions. We will analyse them. ‘We underestimated the speed of the intermediate tyres. We should have stopped Charles a lap earlier or not stopped him at all. Leave him out, protect the position and send him directly on the dry tyres. ‘It will serve as a lesson. We want to make up for it as soon as possible. We know the car is fine, the drivers are in good shape, but there are no smiles in the team – we are all disappointed. ‘But without pointing the finger at anyone, this team wants to grow. ’ MORE : Guenther Steiner frustrated with Mick Schumacher after Haas driver’s latest crash at Monaco MORE : Nico Rosberg claims ‘spectacular’ Sergio Perez can challenge Max Verstappen for the title For more stories like this, check our sport page .
