YEADING defender Bobby Behzadi is used to difficult missions - so the job of knocking Newcastle out of the FA Cup should be no trouble at all to the former US Marine.

Behzadi, who was born in Iran, worked for the US Navy for three-and-a-half-years as a personal fitness instructor to some of the country's most highly-trained killers.

His task tomorrow will be to kill off Newcastle's FA Cup hopes and, while United's players might have the edge when it comes to tactics and technique, Behzadi will leave them all trailing when it comes to the stamina stakes.

"When I worked for the US Government I was based in Central London where some of their personnel were stationed," explained the 23-year-old. "Recently though, the base was moved to Naples.

"The fact I was Iranian was never a problem - they were all very friendly.

"Marines are only in the field, in somewhere like Iraq, for a few months at a time, and the staff have to be at a certain fitness level.

"Their level of fitness was very good, as I found out on day one. A guy said he was training for a race, so I went out with him.

"He didn't tell me it was a marathon and I ended up running 16 miles. If I had known, I would have taken a bike."

Behzadi now works in London as a carpenter and, despite spending most of the season on Yeading's bench, is hopeful of nailing down a place in the starting line-up tomorrow.

"I was in Stevenage's youth team when they played Newcastle in the FA Cup," he said. "So I am delighted to be involved.

"I am also a QPR fan so playing on the pitch will be the experience of a lifetime."

* Yeading striker DJ Campbell will be out to make up for lost time when he lines up against Newcastle tomorrow.

The 23-year-old spent ten years with QPR as a schoolboy and then also trained with Aston Villa, before his slapdash approach saw him fail to make the grade with either club.

"I was silly when I think about it," said Campbell, who has already scored 27 goals this season.

"I had a good chance of making it. I definitely regret it, but I was young and I was fiery and I blew it.

"I wasn't willing to listen to people and I did lots of silly things. I'd turn up without a club suit at times when you had to or I'd just be late. I know I let myself down."
