Mo Farah admits he has lost his 'air of invincibility'

World 5,000m champion Mo Farah admits he has lost his "air of invincibility" after his defeat in the 3,000m at the World Indoor Championships in Turkey.
BBC Sport columnist Steve Cram said Farah's fourth place was Britain's "biggest concern" in Olympic year.
And Farah said: "I agree with Steve. You want to keep that invincibility."
But looking ahead to the Olympics he told BBC Sport: "I'm definitely where I need to be. I'm probably a little bit more than what I need to be."
Farah, who won the 5,000m at last summer's World Championships, missed out on a medal in the 3,000m at last weekend's World Indoor Championships in Istanbul.
The Somalia-born Londoner collided with Kenyan Edwin Soi before finishing fourth in seven minutes 41.79 seconds.
At one stage Soi was disqualified, handing bronze to Farah, only for the decision to be reversed on appeal.
Cram, a former world, Commonwealth and European middle-distance champion, said in his BBC Sport column that Farah's fourth successive defeat had handed confidence to the Briton's great rival Bernard Lagat, who clinched gold in Turkey.
However, Cram added there was no need for Farah to "press the panic button yet".
Farah said: "Steve's an athlete and I have a lot of respect for him, and what he was trying to say.
"He just said 'as an athlete, you just want to keep winning, you don't want to lose to another athlete'."
Farah said that competing at the world indoor event "was always fun and games", adding "at the same time I wanted to do well".
He said his next race would be the Bupa London 10km in May and he would return to Portland, Oregon, to train until then.
