Former world 400m hurdles champion in search of new coach after being guided by Arnold and based in Bath for past five years

Hurdler Dai Greene has announced he has parted company with coach Malcolm Arnold after five years of being based at the University of Bath.

He explained how is is need of a "change of scene", with the 28-year-old having suffered injury problems over the past couple of years. Arnold - one of the world's most respected hurdles coaches - guided Greene to his world 400m hurdles title in Daegu in 2011, as well as gold medals at the 2010 Commonwealth Games in Delhi and the 2010 Europeans in Barcelona.

"I could do with a change of scene so at the moment I'm in search of a new coach," Greene told Sport Wales.

"I've been in Bath for around five years and I feel that the last couple of years haven't gone my way.

"It can be a little bit depressing going to training when you're the only guy injured and training on his own."

The Welshman, who has a best of 47.84 clocked in 2012 which places him second on the UK all-time list, has only raced twice this season and he failed to progress from the heats when defending his Commonwealth title in Glasgow this summer.

But his split from Arnold is an amicable one and he described the senior performance coach for UK Athletics as a "great guy".

"I've learned so much under his tutelage and if it wasn't for him I wouldn't be sitting here, I wouldn't be being interviewed, I wouldn't have had the medals I have won,” said Greene, adding how Arnold will be assisting him in his move between coaches.

"It was mainly the change of location for me that was the driving factor, the need to have more people around me at an elite level, especially when I've had lots of injuries.”
