Paula Radcliffe has questioned the controversial UK Athletics decision to appoint Linford Christie as a mentor to Britain's sprinters.
UKA turned to Christie even though he was banned for two years for testing positive for nandrolone in 1999. Radcliffe, asked if she thought it was the right choice, said: "Personally, I don't believe it is. It has to be someone athletes can look up to.
"We also have to make sure as a country that we are leading the way in competing fairly and not taking short cuts."
Radcliffe, asked about Britain's meagre medals haul in Gothenburg going into the final day's action, said: "It is a disappointing showing and a disappointing medal tally and there are a lot of things we need to look at improving for the future but there are promising young athletes like Becky Lyne coming through."
* UK Athletics performance director Dave Collins has defended the decision to send Harry Aikines-Aryeetey to train with Justin Gatlin's coach, Trevor Graham.
Aikines-Aryeetey, aged 17, trained alongside the American Olympic champion Gatlin and Graham in April, three months before Gatlin tested positive for an excessive level of testosterone.
Graham has been banned by the United States Olympic committee from their training facilities because of his record of mentoring athletes who have used performance-enhancing drugs.
Doping bans imposed on ten athletes who had trained with Graham were public knowledge when world youth 100 metres and 200m champion Aikines-Aryeetey went to work with him in North Carolina. Collins defended the decision and felt the young athlete's experience in the United States was positive.
"We've got to compete against these people and we have to learn how can we beat them, and that means you look at what else they do," Collins said. "I've competed against people who have been on drugs (as a judo player). I beat them sometimes. Is there something we can learn from what they do, bar the pharmaceuticals?
"Of course we can. You look widely around the world at people who have been effective and you see if you can get them involved. We have got to look at international best practice.
"I was aware of some aspects of (Graham's record) but for me, you would say, 'There is a successful coach. Can we learn from that situation?' because they are doing things that are effective over and above pharmaceuticals. Being successful is not just about pharmaceuticals, is it?"
Up until yesterday, Britain had struggled at the European Championships and Collins accepts that winning medals may be hard work at the 2008 Olympic Games.
"Would it worry me to go to Beijing and not get a gold medal? I wouldn't necessarily be throwing myself out of the window," he said.
"If we went to Beijing with a really good gold medal hope and we didn't compete, then I would be worried. What would faze me would be that we've put in the changes, but we're not seeing people step up to the plate."
