quite magnificent save. Joshua King's introduction, at the expense of left-back Tyler Blackett, added pace to the attack but Posh were rarely troubled again until the closing few minutes.
Reds Academy product Ajose wrapped up the victory on 82 minutes by calmly beating Johnstone after being set up by Paul Taylor's astute pass to promote his claims to stay at London Road. Taylor forced Johnstone into more action before the final whistle as Darren Ferguson's side deserved the triumph in the end, while King failed to provide the finishing touch after a couple of positive runs at the death.
