Preston manager Graham Westley felt his side's performance in the 1-0 FA Cup defeat to Millwall was worthy of a replay.
Liam Feeney's strike just before the half-hour mark proved to be the difference between the two teams at the New Den on Saturday.
The Lilywhites pushed for an equaliser after the break, with the best chance falling to Stuart Beavon, whose eight-yard shot flashed just wide.
Westley was left to rue what might have been, saying: "We feel we put in a good enough display to get the goal that would earn us the replay but things are as they are unfortunately.
"When you go in one-nil down at half-time you're always trying to look to make a difference to the game and if you can get a grip in midfield, which we did second half, then you have a platform to build on.
"We mixed the midfield around which gave us some impetus going forward.
"We try to look at the team performance rather than individuals, and from our point of view it was never going to be easy to come to their patch as they're flying high at the moment.
"But the key is for us to look at the improvements we need to make that will make the difference between the results we're posting and the ones we want."
