Lewis Hamilton’s recent conduct at Ferrari has been criticised by Ralf Schumacher, with the German suggesting he’s causing more problems at the Maranello outfit.

Hamilton recently admitted to telling team boss Fred Vasseur to ‘calm down’, after the Frenchman approached the seven-time champion about his comments over team radio at the Miami Grand Prix.

Those team radio messages included Hamilton expressing his displeasure at how long it took for the team to orchestrate team orders between himself and Charles Leclerc, telling engineer Riccardo Adami to: “have a tea break while you’re at it.”

Ferrari are sat down in fourth in the constructors’ championship with the team having accumulated just one main race podium across six grands prix weekends, while seven-time champion Hamilton is sat in seventh in the drivers’ standings.

Schumacher takes aim at Hamilton

It’s not the first time this season that Schumacher has singled out Hamilton during Ferrari’s struggles. The German ex-F1 racer recently suggested that Hamilton may quit Ferrari before his contract is up, due to his poor form.
