Oxford United supporters are being offered the chance to be Jim Smith's assistant for the day - and help him decide on substitutions and tactics.

The role of U's assistant manager is being auctioned as part of Peter Rhoades-Brown's testimonial against Chelsea on Monday, April 30.

The highest bidder will be given the chance to help Smith give the pre-match team talk, sit on the bench alongside the Bald Eagle, pose for the team picture beforehand as well as having a say on what players come off, and where they play.

It may be your chance to play Matt Elliott on the wing, get 'Chicken' George Lawrence to track back, or even substitute England boss Steve McClaren!

Other big names who you could haul off include Joey Beauchamp, John Durnin and Jim Magilton - although Rosie has stressed that it will coast extra for him to come off.

Rhoades-Brown has been handed a testimonial after more than 20 years service to Oxford, and tickets have been selling well.

But the former Chelsea winger is hoping for a couple of things to go his way before the big game - namely Chelsea being knocked out of the Champions League.

If the Blues are out, Jose Mourinho has promised to send some big-name stars.

"I'm going to be sitting at home wearing a Valencia shirt for the next week or so hoping they can do it," Rosie joked.

"But seriously, we think that the idea of being Jim's No 2 is a great one for United fans.

"The chance to work alongside one of football's great managers doesn't come along very often.

"And for Oxford United fans, it could be the chance of a lifetime."

The auction is only available to over 18s, and can be found on http://www. specialistauctions.com.auctiondetails.php?id=519702.
