FC United manager Karl Marginson believes sealing a third successive promotion would rank as the breakaway club's greatest ever achievement.

The Rebels face Skelmersdale United in the play-off final at Gigg Lane tomorrow with a place in the UniBond League Premier Division up for grabs.

And, in a campaign best by injury problems and a hectic fixture pile-up, the United boss admits it would eclipse any other success in the Reds' short history.

"With the amount of injuries we've had coupled with the fact that we've had to play 22 games in the last five weeks, promotion this season would be the best yet," said Marginson.

"It's the biggest game in the club's history. We've said it before but that's the beauty of being at a club which was only formed three years ago."

Goals from Adam Carden, Rory Patterson and Jerome Wright helped the Bury-based club, who have already won the Presidents Cup, overcome Bamber Bridge 3-2 in Wednesday night's semi-final clash. And Marginson believes his side will take confidence from that victory into the weekend's clash with the Merseysiders.

"It's going to be very even like the Bamber Bridge game, but we know we can beat anyone on our day," he said.

Marginson is waiting anxiously on the fitness of captain and centre-back Dave Chadwick, who is struggling with a strained hamstring.

Adam Turner will continue in his absence if he does not make it, while full-back Shaun Roscoe will deputise for the suspended Bradley Howard.
