Here are our suggestions! There are former Posh players and future top-class stars amongst them.
Let us know which League One players you think Posh boss Darren Ferguson could sign to enhace his current squad.
1.
Accrington Stanley: JORDAN CLARK (red) is one of the best players in League One according to Posh boss Darren Ferguson and who are we to argue? He's a wide player comfortable on either flank and scores valuable goals. Photo: PA
2.
AFC Wimbledon: MARCUS FORSS. We're cheating really as Forss (blue) went back to parent club Brentford in January after a superb loan spell at Wimbledon. Scoring 11 goals in 17 starts for such a poor side is a fine effort and the striker is only 20. Photo: Worthing
3.
Blackpool: ARMAND GNANDUILLET is enjoying an 18-goal season by the seaside, the best of his career. He's big and strong and an ideal Plan B for Posh if their cultured, pacy style isn't working. Photo: Midlands
4.
Bolton: LUKE MURPHY. Posh tried to sign this dashing, stylish midfielder when he was at Crewe, but for some strange reason he chose to move to Leeds United instead. Posh reportedly tried to sign him again last summer, but he decided to stay at Bolton for financial reasons. Now that really is strange. Photo: atex.scriptmanager
