Leyton Orient face Peterborough United tomorrow in the first leg of their semi-final with a place in the League 1 final at Wembley on the line.

The O's travel to London Road for the opening leg, with a 12.15pm kick-off, while the return match takes place on Tuesday night.

Russell Slade's side produced arguably their best performance of the season to win 3-1 at Peterborough in November but lost 2-1 in the home match back in February.

Orient have it all to do against play-off specialists Peterborough with their opponents having won on the three occasions they have taken part in the end of season competition.

Darren Ferguson's side finished in sixth place but ended the campaign reasonably well as they won four of their last six games.

The Posh are unbeaten in their last five home matches dating back to the defeat against play-off contenders Rotherham in March. 

Britt Assombalonga is the main threat for Peterborough with the striker having scored 32 goals in all competitions for them this season. 

But the O's have plenty of attacking talent at their disposal with strikers David Mooney and Kevin Lisbie scoring seven goals in their last three matches played together.

Slade should be able to call upon a fully fit squad with defender Scott Cuthbert expected to be available after missing the MK Dons win with a hip injury.
