Sheffield United boss Paul Heckingbottom has claimed Forest were fortunate to have not given away a penalty in the Reds' 2-1 win on Saturday.
Forest got their play-off campaign underway with a positive showing at Bramall Lane as goals from Jack Colback and Brennan Johnson gave them the advantage. Sander Berge scored a late goal to reduce the deficit for the hosts, but they still have work to do when they head to the City Ground on Tuesday (May 17) night for the second-leg.
The visitors dominated proceedings during the first-half and could have been well out of sight had Sam Surridge and Johnson converted the chances they had.
