One thing for sure is that Posh should line-up with a diamond.
The PT has picked its side for the match below.
1. DAI CORNELL
Made a fantastic save late on against Millwall to preserve the lead. So often I've found myself saying there's nothing not much he could have done with the goals, as a sort of compliment but he deserved credit for some of the big saves he's made in matches.
2. JOE TOMLINSON
Even if you'd have told me Dan Butler had made a miracle recovery, Tomlinson still has to play. His set-pieces and general passing ability are something Posh have been missing all season. With the diamond, it puts more pressure on the crossing ability of the full-backs and he has it in spades.
3. RONNIE EDWARDS
Blackpool have a pacy forward line so it will be an interesting test for Edwards, who is not blessed with pace for such a young man. He has stood up to most challenges thrown at his this season though, so I back him.
4. JOSH KNIGHT
I thought Fergie was a little harsh in the week when he said his partnership with Edwards had done ok. He is finally getting up to the level of player we thought Posh were signing in the summer.
