The struggling J-League side were said to be considering an approach for the 28-year-old striker, according to a report in Japanese daily Nikkan Sports.

JEF United have admitted Owen would be a great signing but stressed no approach has been made as spokesman Kentaro Shiga told PA Sport: "We are considering adding players to our squad when the transfer windows open this summer. However, we haven't come to the point where we can name the possible candidates, including Owen."

Former Liverpool first-team coach Miller was recently unveiled as JEF United's new manager and is keen to add to his squad when the transfer window opens.

JEF United are currently bottom of the J-League with just one victory and Owen, who has yet to agree a new contract extension with Newcastle, was reported as being the ideal solution to their goalscoring problems.

The spokesman added: "It would be great if we can have a player like Owen with us as that will increase the attention in our club. But we have just started under our new manager and are still working to put things together in the new administration."

Newcastle declined to comment on the speculation.

Meanwhile, Toon boss Kevin Keegan is confident winger James Milner will be fit for the start of next season.

The 22-year-old had been due to return to the Magpies' side against Everton on Sunday after two months out with a foot injury but suffered a slight setback in training.

"He got right back to being ready to play but when he was shooting last week he felt a slight twinge," Keegan told www.nufc.co.uk. "There is a slight problem with his ankle and he's had an injection."
