Britain's athletes won four medals in Beijing – one gold, two silver and one bronze – the same number as in Athens four years ago but one below the pre-Games target.

That performance has been put in the shade by sports such as cycling, rowing and sailing and led to speculation over Collins' future, but the 54-year-old said today: "I certainly haven't heard anything from my CEO or chairman while I've been here.

"I'm just continuing to do the same job that I've been doing, which is to try and take things forward to make sure we have all we need to make this a strong sport through 2012 and beyond."

Asked if he could categorically state Britain would win more than four medals on home soil, Collins added: "I can't categorically promise but I am very confident. I would say it's a pretty good bet. I'd bet my job on it."

Collins, a former marine appointed in December 2004, added: "I would question the way I'm working and what I'm achieving a good deal more than anyone else and that's essential.

"You have to look very carefully and consider if what you're doing is the right thing. You take a lot of steps to make sure it's the right thing, you audit your decisions, you make things a team decision.

"It's of interest to me that four or five of the other governing bodies in Europe want to come and have a look at what we're doing because we've had a really good Games. My perception would be that we haven't done as well as we want to, nor as well as we need to do. We will go back and review the heck out of this and learn the steps we need to take forward.

"I'm very satisfied in the steps we've made. If other people aren't, then that's their decision and I have to abide by it. I have heard nothing so I will continue to carry on working."

Collins, whose current contract runs until March 2009, added: "I think I've done the right things. There are challenges. It's a necessity to have a coherent and consistent leadership so we are all working in the same direction. I don't think it's unfair of me to sit here and say we were very very close, that we might have had two or three more medals, but that shouldn't change the fact that we are doing the right things in the right way.

"If the plan that I've got is going to be agreed by my management and they're going to be supportive of it, then we're going to move forward. If not, I need to know and we can move in a different direction. I think I should be judged on more than the medal count, you need to drill down and look at the performance further down the line.

"I'm disappointed with the performance, but frankly our position in Helsinki was not great (Paula Radcliffe won the only gold of the world championships on the final day), our position now is much stronger."
