Button believes that Hamilton's calm demeanour has started to 'hurt him' at Ferrari

Following the qualifying for the Miami Grand Prix, Button spoke to Sky Sports F1 about the difference between Hamilton in his McLaren days and now. “Lewis is a different character now than he was when we were teammates,” he said. “If he was deflated, the next day he was out and on it and super fast. Now, he’s much more of a calm personality, he’s much more of a rounded character.”

Although such a calmer approach may work well for some drivers, Button thinks it is actually working against Hamilton – especially now that he is consistently slower than his teammate at Ferrari. “I think it is starting to hurt him a little bit, constantly being slower than his teammate,” he said. “That’s not how Lewis Hamilton is built. He’s a winner.”

After the Formula 1 race in Miami, Ferrari's team radio communications sparked plenty of debate. Both drivers voiced frustration over how the team handled their strategy—particularly the late call to swap positions while Hamilton, on fresher tyres, was pressuring Leclerc from behind. Eventually, Hamilton was told to return the position, adding to the confusion and dissatisfaction within the team.

Hamilton’s frustration came through loud and clear over the radio, with a series of sarcastic remarks aimed at the team. At one point, he joked about having a tea party, and later, when told Carlos Sainz was closing in, he quipped whether he should let the Williams driver through as well.
