SOUNDBITE (English): Greg Rutherford (on defending his Olympic title)

"I think I have as good a chance as anybody and we have figured things out, I will be going back to work in Arizona at the World Athletics Center which has been fantastic and going forwards it is something that is going to be key for me. If I can get myself in the same position as in 2012 then I can definitely win it again and that is what I am gearing towards".

SOUNDBITE (English): Greg Rutherford

"I don't think it adds pressure but it makes it more exciting for me, and the win if I can get it at the World Championships make me only one of five people that would have held all the titles at the same time in British history so it makes it exciting. I love the pressure and looking at the world of long jump I have got as good a chance as any if not better than most so that it what I am aiming towards and I am confident I can do it".

SOUNDBITE (English): Greg Rutherford (on the doping allegations surrounding Mo Farah's coach Alberto Salazar)

"My stance is if somebody is cheating then there should not be involved in sport but until it is proven you cant go on a massive offensive and say anybody who has had a drug allegation then we need to get rid of. Until it is proven you just have to stick with what is going on and leave it up to the professionals to find that out. With regards to UK Athletics I have no idea what their working relationship is with the likes of Alberto Salazar. If it came out it was something bad then I assume they would not work with them anymore but until something is proven we can't speculate on that."
