"I am thrilled to have won and to have played so well for 65 minutes of the game, but finished feeling we had got away with it - and but for goalkeeper Luke Steele in the last 25 minutes we would have lost.
With a three-goal lead we should have been managing the game better especially against a side showing the unbelievable creativity of Peterborough.
We have to learn not to underestimate opponents, as you can never legislate how teams will come back."
Keith was talking to SKY Sports.
