Goals from Dave Kitson and Aaron Mokoena handed Pompey a fifth straight league victory and at the other end Jamie Ashdown kept a fifth successive clean sheet. Cotterill said: "I don't know whether 47 points would actually do it (be enough to avoid relegation). I think it's more likely to be 48. I don't think it will be 50 or 52. But we're not too far from the play-offs either.
"You have to set your goals and targets high because if we fail (to reach the play-offs) and end up in the top half of the table this year, what a good season that would be, considering everything that has gone on.
"I'm sure there will be a lot of teams equally as big as us who would give their right arm to be where we are.
"All credit to the lads - they've kept their heads down and carried on working. Hopefully they're getting a few rewards now."
