League One: Orient v Sheffield United, Saturday 3pm.

Orient have the chance to climb out of the bottom four for the first time this season when they entertain Sheffield United on Saturday.

O’s go into the match having taken 10 points from their last four games and manager Russell Slade is likely to stick with the 4-1-4-1 formation that has given them that success.

“We have found a shape and a formation that has made us a little bit more solid and our recent form has been that of a top seven side,” he said.

O’s then travel to Yeovil on Tuesday night and Slade admitted:“They are all big games at the moment because we had such a poor start. It means that every match becomes more intense in a way.

“But we have to keep digging out results and not get carried away.”

Orient defender Ben Chorley is back in contention, which gives Slade an interesting selection call after Terrell Forbes and Scott Cuthbert played at the heart of the defence against Bury on Saturday and kept a clean sheet.

However, midfielder Jimmy Smith is unlikely to return. “He has suffered a slight setback,” confirmed Slade.

Smith pulled a thigh muscle in training the day before the Huddersfield Town game.

“It turned out to be a little bit more serious than we thought,” admitted Slade.

“He has had to take a step back, but is not that far away now.”

On-loan Spurs keeper Ben Alnwick has also suffered a setback.

“He had a serious groin tear, but made rapid progress at first,” said the Orient manager.

“But he has suffered a couple of small set backs and is not 100 per cent fit yet.”
