Parkinson told reporters: “We have to show we’re serious contenders at this level and we’ve done it in really good style. We knew what we had to do today against a very good Peterborough side, the shape of the team out of possession was outstanding.
“The first goal typified our quality and all in all it was good win for the team and the subs who came on. It was the shape of the team and the structure was really good, Peterborough found it difficult to play through us.
“We were reasonably comfortable and the lads are on a high because of that. This was another test for us today.”
