Leyton Orient face a crucial trip to League One relegation rivals Crewe Alexandra this weekend. 

The O's head into tomorrow's clash just one place above fourth bottom Crewe in the table. Orient are unbeaten in their last three games and will be looking to complete the double over them after beating them 4-1 in November. 

Orient have not been beaten by Crewe in the last seven meetings but manager Fabio Liverani is not taking anything for granted. 

“The league is unpredictable,” Liverani said. “We went to Coventry and they had won three of their last four games and we won.

"We respect Crewe but we don’t fear them and we know our abilities so we will go there to do our game.”

Midfielder Marvin Bartley could be added to the squad after missing Monday's draw with Gillingham due to a hamstring injury.  

Crewe's form is on the slide with a 2-1 victory at Sheffield United their only win in the last six matches.
