Leyton Orient captain Nathan Clarke has described this evening's play-off second leg tie with Peterborough United as a "life changing match".

The O's host Peterborough tonight with the match in the balance at 1-1 after Saturday's first game. The winners will advance to the Wembley League 1 final on Sunday, May 25.

Clarke said: "It's a life changing game on Tuesday night for a lot of people and we are desperate to come out on top."

The Orient defender insists the team still have plenty of work to do if they are to end Peterborough's 100 per cent record in the play-offs and reach the final. 

Clarke said: "We've still got to do the job, score the goals and be strong in defending.

"Either way, home advantage is nice but we've still got to get the job done. It will be a packed crowd and the messages we're getting from the supporters this week are all really positive.

"It's half-time in the tie and we couldn't have won it but we could have lost it if we weren't switched on and focused.

"It's only half-time and the job's not done yet. It's about doing things right now until Tuesday night."
