Postecoglo said, "I thought it was pretty good. I thought it was important we put in a decent performance today and won the game for a number of reasons. I thought the lads handled it pretty well.
"It's always a bit difficult last game of the year, Sheffield United don't have anything to play for, so it can be easy to kind of not have to right mentality but I thought for the most part we had that tonight.
"Three goals... I thought Wes Foderingham was outstanding. Overall I think it was an important win and a good performance.
"I thought Deki was good. He's worked awfully hard this year without a lot of reward in the front third. We thought playing him through middle today would help us with his mobility and ability to run in behind. He did well.
"He always works hard but it's that sort of final third where we need him to get rewards and he got them today so he did well."
