Forest were the last to beat Swansea City in the league but that was almost three months ago when Forest themselves were in the middle of a long unbeaten run.
And the Swans now have the chance to continue the run of their own tomorrow and move within two points of their hosts with a game in hand which will act as a second incentive for the Swans although Pratley insists they are out to seek revenge for that defeat at the Liberty
"We'll be going there trying to end that nine-match unbeaten run," he said. "It's got to end some time.
"We owe them one to be honest. They beat us at our home ground so we want to go there and get a little bit of revenge against them.
"Obviously they're third, we're fourth, but it's three points and we'll be going there trying to win like we do every game.
"They know how to win games, but they've had a little bit of a dip in form away from home in their performances and results.
"They've come up from League One and we knew they're a good team, we knew they'd spent a lot of money in the summer to try and get into the Premier League."
