Lewis Hamilton called on Ferrari to issue rules of engagement after the home team’s Italian Grand Prix ended in embarrassment and acrimony.The seven-time world champion finished sixth after a first-chicane altercation with his team-mate Charles Leclerc, who then crashed out in a 160mph smash that saw him taken to the medical centre, where he was declared ‘OK’.After going wheel-to-wheel with the Monegasque, he came on to the radio to say, quite rightly: ‘Charles pushed me off.’Hamilton got as high as third place at various stages yesterday, eliciting huge cheers from the partisan crowd, before dropping back on fading tyres. But it was the management of the two drivers rather than any strategy complaints that was top of his agenda at the end of the race won by Mercedes’ wonderkid Kimi Antonelli.In a message to team principal Fred Vasseur, the seven-time world champion said: ‘Here there are no rules. And that’s something that needs to change. When I was at Mercedes we had written rules of engagement. And we never had it too bad.‘There was a moment with me and Nico a couple of times. But more often than not, it was good. Here there are no rules. Lewis Hamilton was furious when he was pushed off the track during the opening lap The two Ferraris make contact with Hamilton (left) being squeezed out by his team-mate Footage from Leclerc’s car showed the two coming together, with Hamilton forced off‘I don’t race dirty. I’ve always raced clean, and fairly, and always left space. So I don’t think they should be worried about me. I’ve come into the team and tried to be respectful of space. And definitely not to put the team in jeopardy. And I stand by that.‘That’s all I can talk about on my side. You’d have to speak to Fred about the other side and decisions taken there.’The next round, the 14th of 23, comes next Sunday in Madrid in the city’s first staging of the Spanish Grand Prix.Hamilton, who fell 76 points behind leader Antonelli, reflected on his dreams of an eighth world title, saying: ‘It’s never over until it is over. With the pace Mercedes have, it’s a very difficult amount to close.’‘We didn’t do so well today, but it’s painful to badger my guys. They go home to their families. And they are working really hard.‘But it isn’t good enough. We’ll go back to the drawing table.’
