Rosberg delivers verdict Hamilton won't want to hear on Ferrari team orders

Speaking to Sky Sports F1 following qualifying at the Italian Grand Prix, Rosberg addressed suggestions that Ferrari should back the seven-time champion in the title fight. "They can't do that," said Rosberg, who was partnered with Hamilton at Mercedes from 2013 to 2016. "They have two No. 1 drivers, both on a similar level. You cannot, now in the middle of the season, put everything just working towards Lewis. It's way too early, and that doesn't make sense."

Rosberg acknowledged that the internal fighting has been costing Hamilton championship points, but insisted the team simply has no alternative. "Of course, it costs them performance, and Lewis championship points eventually, but the team cannot do that at this stage against Leclerc. It's not feasible," he added.

Rosberg's verdict carries particular weight because he lived through the exact arrangement Hamilton is now demanding. Hamilton has called for rules of engagement similar to his time at Mercedes with Rosberg, as GPblog reported on Sunday.

That famous document, created by then-Mercedes strategist James Vowles, was designed to prevent on-track clashes between Hamilton and Rosberg during their consecutive fierce title fights between 2014 and 2016.

It could not prevent every explosive flashpoint, most notably the 2016 Spanish Grand Prix collision that wiped out both Mercedes cars. Rosberg, who announced a shock retirement just five days after winning his maiden title in 2016, is now essentially telling Hamilton that Ferrari cannot replicate the same level of structured support mid-season.

Sunday's race at Monza only underscored the dysfunction. Hamilton tried to force his way past Leclerc on the inside at the first chicane, with the Ferraris running side by side through the corner before Hamilton was forced to take to the gravel. Leclerc then crashed heavily on the exit of the Parabolica on lap two, bringing out a red flag. Hamilton finished sixth, while Antonelli produced a sensational comeback from 19th on the grid to take victory, stretching his championship lead even further.
