What an impact he has made at London Road. Six goals and three assists as he helped propel Posh to the top of Sky Bet League One.
Commanding in the air, skilful on the floor, the on-loan Scot has formed an instant partnership with Matt Godden.
Peterborough manager Steve Evans said: “He came into us and he wasn’t in the best condition. I don’t think he believed he had a future at Nottingham Forest under Aitor [Karanka] but it took me a few weeks to persuade Aitor to let him come to us.
“With Jason, it was instant: he wanted to come and play for a manager who tried to sign him before, when I was in the Championship with Rotherham. So he has worked incredibly hard to get fit. He is a fantastic kid. He brings a real laughter to your dressing room most days. He brings a real unity to your dressing room, and he’s ably assisted by some wonderful players.
“I think when Jason was very successful at Hibs – his goal record was up there with the best in Scottish football – he scored a lot of goals when he played with a strike partner. It’s very easy to take him away and think you can play him as a one. But playing as a one versus playing as a two, is sometimes like asking a bricklayer to do the plumbing. It’s a completely different role.
“He does complement our second striker – and Jason does a lot of the work as well – and playing in a two he will always score goals.”
Cummings said: “Any of the boys could have won this, so I will dedicate this to the boys as well. We have been unbelievable so far, and it is early doors so we don’t want to get too carried away, but hopefully it continues. It is the best start I have had so far and I am just enjoying my football at the moment.
“I am playing in my favourite formation, my favourite position, which is two up front and it is just like playing with your best mates. The boys are all down to earth, they are good lads and got good banter. We have just started so well and I hope it continues.
“For a striker I am getting chances every game. Fair play to all the boys who have been different class, I couldn’t have won this without them. They set it up for me, they’ve won me a few penalties, and made my life easy. I just tap it in at the end of the day and get all the headlines!”
Sky Sports’ EFL pundit Don Goodman said: “Cummings is relishing the opportunity to be the main man after finding opportunities hard to come by at parent club Nottingham Forest and Rangers last season.
“In a team that have been scoring for fun, Cummings seems to be at the centre of everything, scoring goals as well as laying them on for his teammates.”
