Blues skipper Adam Barrett knows his side face a very tough task against Leeds on Saturday, but believes they are up for the challange, even as the Shrimper injury problems continue to mount up. Barrett: Shrimpers skipper and all round legend Adam Barrett is well aware his team are up against it when they travel to Elland Road at the weekend to face Leeds United.They may have been in stuttering form recently to drop out of the automatic places but with Southend's confidence hardly high and facing potentially their ninth successive loss on the road, they will do well to return with anything.Striker Scott Spencer has now added to manager Steve Tilson's woes by being ruled out for the rest of the season with an ankle injury. But Barrett has called on his remaining team-mates to hit top form against the promotion-pushing Yorkshiremen. "We are really down to the bare bones now so it's going to be a tough ask, but we have to believe it's possible for us to go and win there," said the centre- back. It's bad news about Scott, especially as we have a such a small squad, but what better place is there to go and win than Leeds. They are the biggest team in the league and I'm sure there will be a great atmosphere in the ground, so it's going to be incredibly difficult. But if we have a good team shape and fight hard then hopefully we can nick something from the game." Spencer will be joined on the sidelines by Franck Moussa, who is suspended, and broken foot victim Damian Scannell. Alan McCormack is also doubtful with a foot problem and will face a late test on his fitness. Blues are desperate for points in their fight against relegation as they remain three points from safety. But Barrett insists his side will not throw in the towel. "It's all still to play for down there. We're certainly not dead and buried and one win could make a big difference. We just need it to come soon because that would really boost our chances. There are a lot of teams involved and they aren't all winning so we can still get out of trouble, but it's getting more and more difficult all the time."
