Alonso will leave McLaren - Head

Fernando Alonso has not behaved "as a sportsman" and will leave McLaren at the end of the season, says Williams' engineering director Patrick Head.

"I would expect Alonso to either have a long time gardening next year or to go to another team," Head told BBC Sport.

"I suppose his relationship with McLaren boss Ron Dennis could be repaired, but I'd be surprised.

"I think it's unfortunate that it's got to this point, but that's the way it is," added the Williams co-founder.

"McLaren are a very, very fair team in the way they treat their two drivers.

"Fernando did not contemplate that there would be this young chap, Lewis Hamilton, who would be beating him, and he has reacted to that."

Who will win the title on Sunday?

Alonso goes into Sunday's final race of the season in Brazil trailing team-mate Hamilton by four points in the drivers' standings.

And while Head acclaimed Hamilton as "a hugely impressive" performer, praising him for being "adept at avoiding problems", he was less complimentary about Alonso.

"From what I've seen, it does not look to me, or to many people in the pit-lane, as if Fernando has handled himself particularly well as a sportsman," he said.
