Greg Rutherford exited the World Championships at the first hurdle but believes his selection for Moscow was a "no brainer" despite furious criticism from rival Chris Tomlinson.
A year on from winning Olympic gold, the selection of 26-year-old Rutherford for Russia was controversial.
Despite struggling with a hamstring injury, he was picked by UK Athletics performance director Neil Black ahead of the fully-fit Tomlinson.
It was a decision that backfired as the Milton Keynes athlete finished 14th in qualification, managing a best of 7.87 metres - well shy of the 8.35m personal best he set last year.
An already irked Tomlinson was furious at Rutherford's performance and vented his fury on Twitter.
"Words can't describe my anger season ruined on media profile & not current athletic form,thanks for the support from the athletics community," he wrote, before hastily deleting the post.
Tomlinson later added: "Thanks for the support,choosing not to tweet (again) will regret it when my blood pressure settles!! Good luck to all the team il see u soon."
By that point, though, Rutherford had already been asked about Tomlinson's comment and launched a staunch defence of his selection.
"Ultimately I'm still British number one as it stands and still jumped further multiple times than him this year," he said. "I've beaten him every time apart from when I got hurt.
"I think in any event, no matter what, if you're looking at somebody better whose failed the distance that year but won more head-to-heads and still has a major title behind them, it's a no brainer.
"Surely, you'd pick anyone in any event in the same scenario? Again, Chris is obviously going to be upset but there's nothing I can do about that.
"We both put ourselves in a not-great position by not jumping an 'A' qualifier so that's what it comes down to. We had plenty of opportunities and when speaking to Neil Black, he gave us a two-week extension, he didn't give that to anyone else.
"So we should have got the job done. And it just gave me enough time to get fit. I'm feeling pretty good but just not jumping far enough at the moment. I'm not too concerned about tweets and whatever else."
Wednesday's performance capped a miserable follow-on year for Rutherford in which he has also lost his sponsorship and split with his American coach Dan Pfaff.
After injuring his hamstring at the Paris Diamond League meeting at the start of July, he had pledged not to travel to Russia if he did not think he could win a medal.
So, in hindsight, did Rutherford make the right decision?
"Yeah, I think so," he said. "I genuinely did feel as if I could. We went through so many different tests just to see where I was at.
"I was running really, really quick, hitting the board really nicely in all practice sessions we'd had so there was no reason why not.
"For whatever reason today whenever I took off I just didn't have that extra bit that I've normally had and I don't think there's any way of testing that in competition. You never really know what's going to come out and you've got to bear in mind."
