Hamilton and Alonso are no longer on speaking terms

Hamilton leads the world standings but Jordan says the feud may prove costly.

"It's magic what's happening, but he has to be very careful he doesn't get too political," Jordan told BBC Sport.

"He has to be careful he doesn't say too much that ostracises him or puts him in a position where team boss Ron Dennis has to make a choice."

Whether he likes to believe it or not, Hamilton has a benefit from Alonso being in the team Eddie Jordan

Hamilton was Dennis's protege for several years before making his remarkable entrance into the world of F1.

But while Hamilton has thrived on the track, off it his relationship with Alonso has become strained.

It reached a new low at the Hungarian Grand Prix where Alonso was relegated on the grid for blocking Hamilton in qualifying.

But Jordan said Hamilton needed to recognise that some of his success was down to having Alonso in the team.

"I believe McLaren is giving him a car that's good enough because of what Alonso has brought to the team," he said.

"So whether he likes to believe it or not, Hamilton has a benefit from Alonso being in the team.

"Alonso does feel ostracised. He feels all the team, initially anyway, was going for Hamilton. He was the big story.

"[Hamilton] is playing the media brilliantly, and driving like a champion - at this moment, you'd have to say Hamilton deserves to be world champion.
