Commonwealth heptathlon champion Kelly Sotherton is looking for a new javelin mentor after her poor performance at the European Championships last week.
Sotherton won gold in the Commonwealth Games
Good work in six disciplines was undone by Sotherton's failure in the javelin.
Sotherton has recently been working with one of Britain's top javelin coaches John Trower.
"Obviously I gave my silver medal away to someone who should not be beating me," said Sotherton.
I know it will come if I can find the right person
"One event let me down badly as always and that is being addressed at the moment.
"John has been amazing. He has banged his head against the wall and he has persevered with me but it just hasn't worked.
"I need to do this when my season ends in a month's time with my coach, Aston Moore, and my boss, Dave Collins.
"There have been a number of reasons why the results have been poor.
"If it was mental then I would have trouble with one of the other events.
"It is just a technical issue. It will come. I know it will come if I can find the right person."
