McLaren driver Lewis Hamilton has warned that he could move on to find success elsewhere if their car isn't improved.
The team have backed Hamilton since he was a teenager and gave him his break in the sport, but the Brit claims that he is ambitious and wants to win more titles before the end of his career, which he cannot do with the car in its current state.
It was revealed earlier today that Hamilton would discuss his future this summer, and this is the strongest hint yet that it may lie elsewhere.
"There are a lot of things to take into account. These people have supported me; they got me into Formula 1," he told R-Sport
"I want to win. I'm not that young any more so I want to make sure that whatever I do I make the right decision so I maximise my career."
Hamilton's entire career in F1 has been spent with McLaren.
