Olympic gold-medalist Greg Rutherford is on the lookout for a new coach after part company with United States-based coach Dan Pfaff.
Rutherford, who leapt to glory in the London games last summer on 'Super Saturday', has struggled since then and is yet to break the 8.30m mark this season.
Pole vaulter Holly Bleasdale and Paralympic sprint champion Jonnie Peacock have also ceased working with Pfaff, and Rutherford says the difficulties of working with a coach who is based in Pheonix, Arizona have become too much.
"Ultimately when you've got a coach who is based in America and isn't coming back to Europe particularly, it makes things very tough," said Rutherford.
"I'm in the process at the moment of trying to sort something out."
He added of the frustration of being unable to work with his chosen coach: "I don't want to work with anyone but Dan Pfaff, but things change"
Rutherford showed a glimpse of his best form in Birmingham over the weekend as he finished second in the Diamond League event.
Injury has affected the Milton Keynes-based athlete in recent months, in particular fluid on his knee tendons which has forced him to adjust his technique.
"It's about tying to stimulate my body to remove it, but for whatever reason it's being really persistent," he admitted.
"I'm not able to do the lateral step that I was doing so well last year that was helping me jump so far.
"I'm having to revert back to something I'm not comfortable with. I've spent pretty much this entire year overseas training, trying to get myself back into a decent shape."
